Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV05T10 non- isolated DC-DC converter delivers up to 10 A of output current in an industry-standard through-hole Single In-Line Package (SIP). Operating from a 3.0 5.5 V input, this converter is an ideal choice for Intermediate Bus Architectures where point-of-load power delivery is generally a requirement. The YNV05T10 provides an extremely tight regulated programmable output voltage from 0.7525 V to 3.63 V. YNV05T10 converters provide exceptional thermal performance, even in high temperature environments with minimal airflow. No derating is needed up to 85 C under natural convection conditions. This is accomplished using RoHS lead free solder and lead solder exempted products circuitry, packaging, and processing techniques to achieve are available ultra-high efficiency and excellent thermal management, Delivers up to 10 A (36.3 W) along with a very sleek body profile. No derating up to 85 C The sleek body profile and the preclusion of heat sinks Industry-standard footprint and pinout minimize impedance to system airflow, thus enhancing Single-in-Line Package (SIP): 2.0 x 0.575 x 0.315 cooling for both upstream and downstream devices. The (50.8 x 14.59 x 8.00 mm) use of 100% automation for assembly, coupled with advanced power electronics and thermal design, results in Weight: 0.26 oz 7.28 g a product with extremely high reliability.
