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 of non-isolated dc-dc converters deliver up to 10 A of output current in an
industry-standard surface-mount package. Operating from a 3.0 to 5.5 VDC input, the YNS05S10 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 to
3.63 VDC.
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.
