Description

Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate

Bus Architecture (IBA). The YNM05S05 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, the YNM05S05 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 Y-Series of 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.
