Description
The YS05S16 non-isolated DC-DC converter delivers up to 16 A of output current in an industry-standard surface-
mount package. Operating from a 3.0 – 5.5 V input, the YS05S16 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 YS05S16 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.
