Description
The YM05S05 non-isolated dc-dc converters deliver up to 5 A of output current in an industry-standard surface-
mount package. Operating from a 3.0 – 5.5 V input, these converters are ideal choices for Intermediate Bus
Architectures where Point-of-Load (POL) power delivery is generally a requirement. They provide an extremely
tight regulated programmable output voltage from 0.7525 V to 3.63 V.
The Y-Series of converters 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.
