Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). 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 RoHS lead-free solder and lead-solder-exempted performance, even in high temperature environments with products are available minimal airflow. No derating is required up to 85 C, even Delivers up to 16 A (58 W) without airflow at natural convection. This performance is No derating up to 85 C accomplished through the use of advanced circuitry, packaging, and processing techniques to achieve a design Surface-Mount package possessing ultra-high efficiency, excellent thermal Industry-standard footprint and pinout management, and a very low-body profile. Small size and low profile: 1.30 x 0.53 x 0.314 The low-body profile and the preclusion of heat sinks (33.02 x 13.46 x 7.98 mm) minimize impedance to system airflow, thus enhancing Weight: 0.22 oz 6.12 g cooling for both upstream and downstream devices. The Coplanarity less than 0.003, maximum use of 100% automation for assembly, coupled with Synchronous Buck Converter topology advanced power electronics and thermal design, results in Start-up into pre-biased output a product with extremely high reliability.
