Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an
Intermediate Bus Architecture (IBA). The Y-Series YNV05T100XY non-isolated DC-DC converters deliver up
to 10 A of output current in an industry-standard through hole single in-line package (SIP). Operating from a
3.0 – 5.5V input, these converters are ideal choices for Intermediate Bus Architectures where point-of-load
power delivery is generally a requirement.
The YNV05T100XY converters are available in individual output voltage versions, allowing coverage of the
output voltage range from 0.9V to 3.3V. Each version is capable of providing an extremely tight, highly
regulated and trimmable output.
The YNV05T100XY converters provide exceptional thermal performance, even in high temperature
environments with minimal airflow. No derating is needed up to 85
C
under natural convection conditions.
This is accomplished through the use of circuitry, packaging, and processing techniques to achieve ultra-high
efficiency and excellent thermal management along with a very sleek body profile.
The sleek 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.

Input and Output Impedance
YNV05T100XY converters 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. It is recommended to use decoupling
capacitors (minimum 47μF) placed as close as
possible to the converter input pins in order to
ensure stability of the converter and reduce input
ripple voltage. Internally, the converter has 52uF
(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 47μF-100μF 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 YNV05T100xy has been designed for stable
operation with or without external output
capacitance. Low ESR ceramic capacitors placed
as close as possible to the load (Min 47μF) are
recommended for improved transient performance
and lower output voltage ripple.
It is important to keep low resistance and low
inductance PCB traces when the 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

The same plot is shown in Fig. B with one 470μF
polymer capacitor (6TPB470M from Sanyo) in
parallel with two 47μF ceramic capacitors at full
load.
ON/OFF (Pin 10)
The ON/OFF pin is used to turn the converter on
or off remotely via a system signal. There are two
remote control options available, positive logic
(standard option) and negative logic, and both are
referenced to GND. Typical connections are
shown in Fig. C.
