Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNC12S20 non- isolated DC-DC converter delivers up to 20 A of output current in an industry-standard surface-mount package. Operating from a 9.6 to 14 VDC input, the YNC12S20 converter is an ideal choice for Intermediate Bus Architectures where point-of-load power delivery is generally a requirement. It provides a resistor-programmable RoHS lead-free solder and lead-solder-exempted regulated output voltage of 0.7525V to 5.5V. products are available The Y-Series converters provide exceptional thermal Delivers up to 20 A (100 W) performance, even in high temperature environments with Extended input range 9.6 V 14 V minimal airflow. This is accomplished through the use of High efficiency (0.94 at 5 V output) circuit, packaging and processing techniques to achieve Surface-mount package ultra-high efficiency, excellent thermal management and a very low body profile. Industry-standard footprint and pinout 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 use Coplanarity less than 0.003, maximum of 100% automation for assembly, coupled with advanced power electronics and thermal design, results in a product Synchronous Buck Converter topology with extremely high reliability.
