Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The YS05S10 non-isolated DC-DC converter delivers up to 10 A of output current in an
industry-standard surface-mount package. Operating from a 3.0 – 5.5 V input, the YS05S10 converter is an ideal
choice for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is generally a requirement. It
provides an extremely tightly-regulated programmable output voltage from 0.7525 V to 3.63 V.
The YS05S10 converter provides 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
To turn the converter on the ON/OFF pin should be
The YS05S10 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.
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.
The positive logic version turns the converter on
when the ON/OFF pin is at a logic high or left open,
and turns the converter off when at a logic low or
shorted to GND.
The negative logic version turns the converter on
when the ON/OFF pin is at logic low or left open, and
turns the converter off when the ON/OFF pin is at a
logic high or connected to Vin.
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.
The ON/OFF pin is internally pulled up to Vin for
positive logic version, and pulled down for a negative
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:
The YS05S10 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.
– 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. A:
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.

– 10 K, if the minimum Vin is 3.0 V
ON/OFF (Pin 1)
– 5 K, if the undervoltage shutdown at 2.05 - 2.15 V
is required.
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 ON/OFF
signal referenced to GND. The typical connections
are shown in Fig. A.
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. B). There is no sense feature on the output
GND return pin, where the solid ground plane should
provide a low voltage drop.

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.
A trim resistor, RTRIM, for a desired output voltage
can be calculated using the following equation:

(VO-REQ - 0.7525)
where,
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.
RTRIM Required value of trim resistor [kꢀ]
VOREQ Desired (trimmed) output voltage [V]
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.
When utilizing the remote sense feature, care must
be taken not to exceed the maximum allowable
output power capability of the converter, which is
equal to the product of the nominal output voltage
and the allowable output current for the given
conditions.
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 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.

Safety Requirements
The converter meets North American and
International safety regulatory requirements per
UL60950 and EN60950. The maximum DC voltage
between any two pins is Vin under all operating
conditions. Therefore, the unit has ELV (extra low
voltage) output; it meets SELV requirements under
the condition that all input voltages are ELV.
REXT External resistor between TRIM pin and
voltage source; the value can be chosen depending
on the required output voltage range [kꢀ].
Control voltages with REXT 0 and REXT 15 K are
shown in Table 2.

The converter is not internally fused. To comply with

General Information
2.0
The converter has been characterized for many
operational aspects, to include thermal derating
(maximum load current as a function of ambient
temperature and airflow) for vertical and horizontal
mountings, efficiency, startup and shutdown
parameters, output ripple and noise, transient
response to load step-change, overload, and short
circuit.

Protection Features
Input Undervoltage Lockout
Input undervoltage lockout is standard with this
converter. The converter will shut down when the
input voltage drops below a pre-determined voltage;
it will start automatically when Vin returns to a
specified range.
The figures are numbered as Fig. x.y, where x
indicates the different output voltages, and y
associates with specific plots (y = 1 for the vertical
thermal derating, …). For example, Fig. x.1 will refer
to the vertical thermal derating for all the output
voltages in general.
The input voltage must be typically 2.05 V for the
converter to turn on. Once the converter has been
turned on, it will shut off when the input voltage
drops below typically 1.9 V.
The following pages contain specific plots or
waveforms associated with the converter. Additional
comments for specific data are provided below.
Output Overcurrent Protection (OCP)
Test Conditions
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.
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.
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
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.

120 °C should not be exceeded. Temperature on the
