Prelim. Specification
HBO80A-48-2.5
48Vin 2.5Vout 80A
Basic operation and functions
Pin 2 is the "Enable" pin, connecting a TTL
compatible pin. A TTL control signal to this pin,
according to the specification, will turn the unit on
or off.
The HBO / HBP familyuses planar transformer
technology to achieve high output current. The
whole unit switches at the fixed frequency for a
predictable EMI performance. The HBO / HBP
Brick has many standard controls and protection
functions.
The positive logic version turns on when pin 2 is
at logic high, and turns off when pin 2 is at logic
low. The unit is on when pin 2 is left open.
Input Power ( pin1, pin4 )
The negative logic version turns on when pin 2 is
at logic low and turns off when pin 2 is at logic
high. The pin 2 can be directed to Vin(-), to
enable automatic turn on to the unit without the
need of an external control signal.
Input power Vin(+) must be connected to Positive
input voltage pin1; Input power Vin(-) must be
connected to Negative input voltage pin4.
Output Power ( pin9, pin5 )
Output power Vout(+) must be connected to
Positive output voltage pin9; Output power
Vout(-) must be connected to Negative output
voltage pin5.
Remote Sense ( pin 8, pin 6 )
Permits the user to maintain the accurate output
voltage at the remote load terminals regardless of
the line drop.
On/Off ( pin 2 )
The Sense(-) (pin6) and Sense(+) (pin8) should
be connected at the load or at the point where the
regulation is needed. ( shown on Fig. 2)
Permits the user to maintain unit On/Off, in order
to properly sequence different power supplies
and reduce power consumption during the
standby condition. There are two remote control
options available, positive logic and negative logic
is referenced to Vin(-), and typical connections
are shown in Fig 1.
Fig 2: Remote Sense Circuit
The remote sense feature of the unit
compensates for voltage drop occurring between
the output pins of the unit and load. The Sense(-)
(pin5) and Sense(+)(pin7) should be connected at
the load or at the point where regulation is
required.

Prelim. Specification
HBO80A-48-2.5
48Vin 2.5Vout 80A
If remote Sense is not required, the Sense(-) pin
must be connected to the Vout(-) pin (pin5), and
the Sense(+) pin must be connected to the
Vout(+) pin(pin 9) to ensure the unit will regulate
at the specified output voltage. If these
connections are not made, the unit’s output
voltage will be higher than the specified value.
The unit output over voltage protection senses
the voltage across Vout(+) and Vout(-), and not
across the sense lines, so the resistance between
the output pins of the unit and the load should be
minimized to prevent unwanted triggering of the
OVP.
Fig 3. Trim Up Output Voltage Circuit
For Trim up resistor value, we list the reference
“Trim Up Resistance” for increasing the output
voltage for every 1 percent (see Trim Table 1).
When using the remote sense feature, the output
voltage at the unit can be increased by as much
as 10% above the normal rating, in order to
maintain the required voltage across the load.
Therefore, the designer must consider this
condition.
Fig 5. shows “Trim Up Resistance” value chart.
Trimming down the output voltage for a typical
circuit, as shown on Fig. 4.
Also when using the remote sense function, the
output power must be taken care of, as not to
exceed the maximum power capability of the unit.
Output Voltage Trim (pin 7)
Permits the user to adjust the output voltage up
or down to achieve the custom voltage or to make
the output voltage margining. The adjustment
range is from + 10% to -10%.
Fig 4. Trim Down Output Voltage Circuit
Output voltage can be adjusted up or down, by
connecting the Rtrim-up or Rtrim-down resistor as
shown. Rtrim-up makes the output voltage go up
to 10%; and the Rtrim-down makes the output
voltage go down to 10%.
For Trim down resistance value, we list the
reference “Trim Down Resistance” for decreasing
output voltage for every 1 percent (see Trim
Table 2.).
Fig 6 shows “Trim Down Resistance” value chart.
Leave Trim pin ( Pin 7) open for normal output
voltage.
When trimming up, care must be taken, not to
exceed the unit OVP threshold. A typical circuit is
shown in Fig. 3.

Protection Features
Over Temperature Protection ( OTP )
Input Under-voltage lockout ( IUV )
The unit will shut down when the base plate
temperature exceeds the protection threshold.
Input under voltage ( IUV ) is standard with the
HBO / HBP unit. The unit will shut down when the
input voltage drops below a threshold, and the
unit will turn on when the input voltage goes to
the upper threshold.
The unit will shut down under the base plate
temperature over a 105°C condition to protect the
unit from overheating. The OTP circuit will turn
the unit off when OTP happens. Once the unit
has shut down, it will restart at the cycle when the
base plate temperature goes down.
The hysteretic voltage of the under voltage
protection is 1V, normally from the 34.5V to 35.4V
range.
Output Over-current Protection ( OCP )
The unit will shut down when the over current or
short circuit condition exists.
Once the OCP happens, the unit has shut down.
The attempted restart will continue indefinitely
until the over current or short circuit condition is
removed. When OCP happens, the output
voltage drops below 0.8V.
Input voltage has almost no effect on the current
limit point.
Output Over-voltage Protection ( OVP )
The unit will shut down when the output voltage
exceeds the over voltage threshold.
If the output voltage across Vout(+) (pin9) and
Vout(-) (pin5) exceeds the threshold of the OVP
circuitry, the unit has shut down which is caused
by an OVP circuit, and the unit will never restart,
and the output voltage is below 0.5V.

Application information
Input Source Impedance
The unit has been designed to be stable with no
external capacitors when used in a low
inductance input and output circuit.
If the input source is non-SELV ( ELV or a
hazardous voltage greater than 60 Vdc and less
than or equal to 75 Vdc), for the unit output to be
considered meeting the requirements of safety
extra low voltage (SELV), all of the following must
be met:
However in many applications, the inductance
with the distribution from the power source to the
input of the unit can affect the stability of the unit.
The addition of 100uF electrolytic capacitor with
an Esr < 1W (at 100khz) across the input can
ensure the stability of the unit. Also in many
applications, the user has to use decoupling
capacitors at the output load, to ensure the hold
up time for the load.
·
The input source is to be provided with
reinforced insulation from any hazardous
voltage, including the ac main.
·
·
The input pins of the unit are not operator
accessible.
Safety Requirements and Considerations
For whole system, for safety agencies
requirements, and for the combination of
the unit’s input side (primary side) and the
unit’s output side (secondary side), verify
that under a single fault, hazardous
voltages do not appear at the unit’s output
side (secondary side).
The unit meets the American and International
safety regulatory requirement UL1950. Basic
insulation is also provided between the input side
and the output side.
To meet safety agencies requirements, an input
line fuse must be used external to the unit. An
15A fuse or less with a normal blow rate must be
used to meet the safety agencies requirements. A
minimum 42LFM airflow should also be provided
if the unit is intended to operate at full power
without heatsink.
·
Never ground either of the input pins of
the unit without grounding one of the
output pins. This may allow a non-SELV
voltage to appear between the output pin
and ground.
