The YNS12S16 converter is not recommended for new designs and has been replaced by the YS12S16. Please refer to the YS12S16 data sheet for new product specifications. Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNS12S16 non- isolated DC-DC converters deliver up to 16A of output current in an industry-standard surface-mount package. The YNS12S16 converters operate from a 9.6-14 VDC input. These converters are ideal choices for Intermediate Bus Architectures where Point-of-Load power delivery is generally a requirement. They provide a resistor- programmable regulated output voltage of 0.7525V to 5.5V. The YNS12S16 converters provide exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished through the use of RoHS lead-free solder and lead-solder-exempted products are available circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management and a Delivers up to 16 A (88 W) very low body profile. Extended input range 9.6 V 14 V High efficiency (0.948 at 5 V output) The low body profile and the preclusion of heatsinks Surface-mount package minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The Industry-standard footprint and pinout use of 100% automation for assembly, coupled with Small size and low profile: 1.30 x 0.53 x 0.314 advanced power electronics and thermal design, results in (33.02mm x 13.46mm x 7.98mm) a product with extremely high reliability.
