YM05S05G

The YM05 nonisolated 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.
