Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The YS05S16 non-isolated DC-DC converter delivers up to 16 A of output current in an
industry-standard surface-mount package. Operating from a 3.0 – 5.5 V input, the YS05S16 converters are ideal
choices for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is generally a requirement.
The converters provide an extremely tight regulated programmable output voltage from 0.7525 V to 3.63 V.
The YS05S16 converters provide exceptional thermal performance, even in high temperature environments with
minimal airflow. No derating is required up to 85 C, even without airflow at natural convection. This performance
is accomplished through the use of advanced circuitry, packaging, and processing techniques to achieve a design
possessing ultra-high efficiency, excellent thermal management, and a very low-body profile.
The low-body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing
cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with
advanced power electronics and thermal design, results in a product with extremely high reliability.

Operations
Input and Output Impedance
32
The YS05S16 converter should be connected via a
low impedance to the DC power source. In many
applications, the inductance associated with the
distribution from the power source to the input of the
converter can affect the stability of the converter.
The use of decoupling capacitors is recommended in
order to ensure stability of the converter and reduce
input ripple voltage. Internally, the converter has
44 μF (low ESR ceramics) of input capacitance.

In a typical application, low - ESR tantalum or POS
capacitors will be sufficient to provide adequate
ripple voltage filtering at the input of the converter.
However, very low ESR ceramic capacitors
100 - 200 μF are recommended at the input of the
converter in order to minimize the input ripple
voltage. They should be placed as close as possible
to the input pins of the converter.

ON/OFF (Pin 1)
The ON/OFF pin is used to turn the power converter
on or off remotely via a system signal. There are two
remote control options available, positive logic
(standard option) and negative logic, with both
referenced to GND. The typical connections are
shown in Fig. C.
The YS05S16 has been designed for stable
operation with or without external capacitance. Low
ESR ceramic capacitors placed as close as possible
to the load (minimum 100 μF) are recommended for
improved transient performance and lower output
voltage ripple.
To turn the converter on the ON/OFF pin should be
at a logic low or left open, and to turn the converter
off the ON/OFF pin should be at a logic high or
connected to Vin. See the Electrical Specifications
for logic high/low definitions.
It is important to keep low resistance and low
inductance PCB traces for connecting load to the
output pins of the converter in order to maintain good
load regulation.
Fig. A shows input voltage ripple for various output
voltages using four 47 μF input ceramic capacitors.
The same plot is shown in Fig. B with one 470 μF

logic version. A TTL or CMOS logic gate, open-
collector (open-drain) transistor can be used to drive
ON/OFF pin. This device must be capable of:
When using remote sense, the output voltage at the
converter can be increased up to 0.5 V above the
nominal rating in order to maintain the required
voltage across the load. Therefore, the designer
must, if necessary, decrease the maximum current
(originally obtained from the derating curves) by the
same percentage to ensure the converter’s actual
output power remains at or below the maximum
allowable output power.
– sinking up to 1.2 mA at a low level voltage of
0.8 V
– sourcing up to 0.25 mA at a high logic level of
2.3 V - 5.5 V.
When using open-collector (open-drain) transistor
with a negative logic option, add a pull-up resistor
(R*) to Vin as shown in Fig. C:
Output Voltage Programming (Pin 3)
– 20 K, if the minimum Vin is 4.5 V
– 10 K, if the minimum Vin is 3.0 V
The output voltage can be programmed from
0.7525 V to 3.63 V by connecting an external resistor
between TRIM pin (Pin 3) and GND pin (Pin 5); see
Fig. E. Note that when a trim resistor is not
connected, the output voltage of the converter is
0.7525 V.
– 5 K, if the undervoltage shutdown at 2.05 - 2.15 V
is required.
Remote Sense (Pin 2)
The remote sense feature of the converter
compensates for voltage drops occurring only
between Vout pin (Pin 4) of the converter and the
load. The SENSE (Pin 2) pin should be connected at
the load or at the point where regulation is required
(see Fig. D). There is no sense feature on the output
GND return pin, where the solid ground plane should
provide a low voltage drop.

VOREQ Desired (trimmed) output voltage [V]
If remote sensing is not required, the SENSE pin
must be connected to the Vout pin (Pin 4) to ensure
the converter will regulate at the specified output
voltage. If these connections are not made, the
converter will deliver an output voltage that is slightly
higher than the specified value.
Note that the tolerance of a trim resistor directly
affects the output voltage tolerance. It is
recommended to use standard 1% or 0.5% resistors;
for tighter tolerance, two resistors in parallel are
recommended rather than one standard value from
Table 1.
Because the sense lead carries minimal current,
large trace on the end-user board are not required.
However, sense trace should be located close to a
ground plane to minimize system noise and ensure
optimum performance.
Ground pin of the trim resistor should be connected
directly to the converter GND pin (Pin 5) with no
voltage drop in between. Table 1 provides the trim
resistor values for popular output voltages.
When utilizing the remote sense feature, care must
be taken not to exceed the maximum allowable
output power capability of the converter, which is

The converter is protected against overcurrent and
short circuit conditions. Upon sensing an overcurrent
condition, the converter will enter hiccup mode. Once
over-load or short circuit condition is removed, Vout
will return to nominal value.
The output voltage can also be programmed by
external voltage source. To make trimming less
sensitive,
a
series external resistor Rext is
recommended between TRIM pin and programming
voltage source. Control Voltage can be calculated by
the formula:
Overtemperature Protection (OTP)
The converter will shut down under an
overtemperature condition to protect itself from
overheating caused by operation outside the thermal
derating curves, or operation in abnormal conditions
such as system fan failure. After the converter has
cooled to a safe operating temperature, it will
automatically restart.

between any two pins is Vin under all operating

the condition that all input voltages are ELV.

to the vertical thermal derating for all the output
voltages in general.
The following pages contain specific plots or
waveforms associated with the converter. Additional
comments for specific data are provided below.
For each set of conditions, the maximum load
current is defined as the lowest of:
(i) The output current at which any MOSFET
temperature does not exceed a maximum specified
temperature (120°C) as indicated by the
thermographic image, or
Test Conditions
All data presented were taken with the converter
soldered to a test board, specifically a 0.060” thick
printed wiring board (PWB) with four layers. The top
and bottom layers were not metalized. The two inner
layers, comprised of two-ounce copper, were used to
provide traces for connectivity to the converter.
(ii) The maximum current rating of the converter
(16 A).
During normal operation, derating curves with
maximum FET temperature less than or equal to
120 °C should not be exceeded. Temperature on the
PCB at the thermocouple location shown in Fig. F
should not exceed 120 °C in order to operate inside
the derating curves.
The lack of metalization on the outer layers as well
as the limited thermal connection ensured that heat
transfer from the converter to the PWB was
minimized. This provides a worst-case but consistent
scenario for thermal derating purposes.
Efficiency
All measurements requiring airflow were made in the
vertical and horizontal wind tunnels using Infrared
Fig. x.3 shows the efficiency vs. load current plot for
ambient temperature of 25 ºC, airflow rate of
200 LFM (1 m/s) and input voltages of 4.5 V, 5.0 V

Thermographic imaging is preferable; if this

minimize measurement error. Refer to Fig. F for the
optimum measuring thermocouple location.

The output voltage ripple waveform is measured at
