8. Functions
8-1 Digital control
The converter allows setting of output voltage, sequence and other parameters, and also reading of input
voltage, output current and other information using serial interface PMBus.
The serial interface allows setting of control target values. Since actual operation is influenced by variation
in products, actual and set values will be slightly different.

8-1-1 Internal memory
The converter is equipped with volatile operating memory and non-volatile user store memory. Converter
settings are stored in the user store memory. The contents of the user store memory is copied into
operating memory when power is turned ON.
The control circuit of this converter operates using contents of the operating memory. When settings are
changed using serial communication, they are written into the operating memory. Because the operating
memory is volatile, the modified settings will be lost when power is turned OFF.
To change settings used when power is turned ON, they need to be saved in the non-volatile user store
memory by STORE_USER_ALL command after the operating memory is overwritten.
RESTORE_USER_ALL command can be used to replace the contents of the operating memory with the
data stored in the user store memory (revert to the settings when the previous STORE_USER_ALL
command was executed).
Settings made by the following commands can be stored and restored using STORE_USER_ALL and
RESTORE_USER_ALL commands.

8-2 Output voltage setting
The converter allows setting of the output voltage using serial communication within the range ±15% of the
rated voltage. Since it is not possible to change the output voltage due to potentiometer etc., when output
voltage other than default setting is required, the output voltage setting needs to be changed via serial
communication.

The remote sensing function can be used to obtain good load regulation characteristics on the load side.
The sensing line is a part of the feedback loop, and since it has very high sensitivity, careful attention is
required when making routing. +Sense and −Sense wires should be routed to the load as a twisted pair.
When using this function, the output voltage (voltage between +Vout and -Vout pins) will become higher
than voltage in the output voltage control point (between +Sense and -Sense pins), so make sure that the
output voltage does not exceed the allowable output voltage range. Also make sure that the output power
does not exceed the rated maximum output power.
When using this function, connect Sense Enable pin to S.GND pin. Connect Sense Enable and S. GND
pins at the base of the connector; do not extend these wires.
If this function is not used, leave +Sense, −Sense, Sense Enable and S.GND pins open.
8-5 ON/OFF control function
This function can be used to turn output voltage ON and OFF without connecting or disconnecting the input
voltage. This converter supports ON/OFF control for all output channels at the same time, as well as
individual ON/OFF control for each channel.
The ON/OFF control for all output channels at the same time can be done by two methods: using ON/OFF
pin and serial communication.
Individual ON/OFF control for each output channel can be performed only by serial communication.
It is possible to enable and disable ON/OFF control by ON/OFF pin and by serial communication separately.
ON/OFF control can be enabled and disabled by serial communication. By default, the ON/OFF control by
the ON/OFF pin is set enabled.
ON/OFF control command has a high OFF priority. When ON/OFF control by the ON/OFF pin and by serial
communication are both enabled, the output will not turn ON until both controls are set to ON.
ON/OFF control of the standby power is not supported.
8-5-1 ON/OFF control by the ON/OFF pin
All outputs can be turned ON or OFF by opening or short-circuiting between ON/OFF pin and SB_GND pin.
The ON/OFF pin is connected internally to 3.3V typ. power supply via 10kΩ resistor.
The control logic of the ON/OFF pin can be set to positive logic (output ON when open) or negative logic
(output OFF when open). The control logic of the ON/OFF pin can be set by serial communication. By
default it is set to active high.

sequence.
8-5-2 ON/OFF control by serial communication
Output voltage can be turned ON and OFF by serial communication.
When turning the output OFF by serial communication, it is possible to set whether to apply the turn-off

8-7 Operation monitoring
Information about input voltage, output voltage, output current, device temperature, total operating time and
estimated lifetime of the converter can be obtained via serial communication.
The converter contains 8 following status registers: STATUS_BYTE, STATUS_WORD, STATUS_VOUT,
STATUS_IOUT, STATUS_INPUT, STATUS_TEMPERATURE, STATUS_CML and
STATUS_MFR_SPECIFIC. By checking contents of status registers, it is possible to determine the error
status of this product.
The status registers are set when protection function operates, and contents of the registers are retained
even if the cause of the register setting is removed. However, the status of under voltage lock out is cleared
automatically. The status registers can be cleared under any of the following conditions.
Executing CLEAR_FAULTS command
Reapplying input voltage
Bits of the status register linked to the protection function that latch stops are not cleared even if the
CLEAR_FAULTS command is executed.
When reapplying the input voltage, keep input in OFF state for more than 30 seconds.
The contents of each register can be read via serial communication. For detailed information about
contents of each register, refer to sections describing registers reading instructions.

Since the status register history is saved when the under voltage lock out function is operating, the bit
indicating the under voltage condition is always set.
Since the status register history is overwritten each time the under voltage lock out function operates, it is
not possible to obtain register values other than those that were in the status register at the time of the
latest operation of the under voltage lock out function.
8-9 Under voltage lock out
The converter is equipped with under voltage lock out (UVLO) function preventing malfunction when input
voltage is low. When the input voltage exceeds the activation voltage (79V typ.), the converter starts
switching operation. If the input voltage falls below the deactivation voltage (75V typ.), the switching
operation stops.

8-10 Input overvoltage detection
When the input voltage exceeds the threshold of the input overvoltage protection function, the converter
stops switching operation. Because internal parts are not protected, they can be damaged by excessive
input voltage.
Since this function is a latch-type function, it does not restart automatically. To release the latched condition,
reapply the input voltage. When reapplying the input voltage, keep input in OFF state for more than 30
seconds.
8-11 Output overvoltage protection
When the output voltage (the voltage between +Vout and -Vout pins) exceeds the threshold of the output
overvoltage protection function, the converter stops switching operation. However, the function may not
activate if overvoltage is caused by damaged unit.
When the remote sensing function is enabled, the voltage at output voltage control point (between +Sense
and −Sense pins) and overvoltage detection point (between +Vout and −Vout pins) will be different. So be
sure to consider voltage drop caused by wiring, when setting the protection threshold.
Since this function is a latch-type function, it does not restart automatically. To release the latched condition,
reapply the input voltage. When reapplying the input voltage, keep input in OFF state for more than 30
seconds.
The operation threshold of the output overvoltage function can be configured via serial communication.

8-13 Overheat protection
When measured temperature of the converter exceeds the overheat protection threshold, the overheat
protection function operates, stopping the switching operation.
Since this function is a latch-type function, it does not restart automatically. To release the latched condition,
reapply the input voltage. When reapplying the input voltage, keep input in OFF state for more than 30
seconds.
There is one temperature sensor mounted on the primary side (place shown in the figure below), and there
is also one sensor for each output channel.
The temperature at which the overheat protection function triggers is not the maximum operating
temperature. Therefore, even if this temperature is below the overhead protection threshold, do not use the
converter at temperatures outside the derating range shown in chapter 5.

Parallel operation can be performed by connecting the +Vout pins and –Vout pins of each channel to each
other, and then connecting the CS pins to each other. Always use the remote sensing function during
parallel operation.
Set the same output voltage settings for all output channels used in parallel.
The wiring of +Vout and –Vout pins should have the same length for all output channels.
Load derating is required during parallel operation. Load factor should not exceed 90%.

The read/write target is set by the PAGE command. PAGE 00h to 02h sets the output channel 1 to 3, PAGE
FFh sets all output channels. For example, when turning ON the output channel 1, the output will not turn
ON unless PAGE 00h is set to ON and PAGE FFh is set to ON (the order of setting is irrelevant).
When ON / OFF control by serial communication is disabled using the ON_OFF_CONFIG command (bit 4
or bit 3 cleared), ON / OFF control cannot be performed using this command.

When ON / OFF control by the ON / OFF pin and by serial communication are both enabled (bits 4-2 are all
set), the output will not turn ON until both controls are set to ON.
9-6-5 CLEAR_FAULTS command (03h)
This command is used to clear the status register.
Bits of the status register linked to the protection function that latches the stop state are not cleared by the
CLEAR_FAULTS instruction.
This command only clears the status register, and it does not release the latch stop state set by the
protection.
9-6-6 STORE_USER_ALL command (15h)
This command stores the contents of operating memory in nonvolatile user store memory.
Note: Always maintain the input voltage for 1 second after execution of this command. Otherwise the
contents of the user store memory may be destroyed, making its recovery impossible.
9-6-7 RESTORE_USER_ALL command (16h)
This command overwrites the contents of operating memory with the data stored in the nonvolatile user
store memory.
