Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The YV-Series of non-isolated dc-dc converters deliver up to 25 Amps of output current
in a through-hole (SIP) package. Operating from a 10 - 14 VDC input, the YV12T25 converter is an ideal choice
for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is a requirement. The converter
provides an extremely tight regulated programmable output voltage of 0.80 V to 5.5 V.
The YV-Series of converters provide exceptional thermal performance, even in high temperature environments
with minimal airflow. 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 minimizes impedance to system airflow, thus enhancing cooling for both upstream and
downstream devices. The use of automation for assembly, coupled with advanced power electronics and thermal
design, results in a product with extremely high reliability.
