Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV05T06 non-isolated DC-DC converter delivers up to 6A of output current in an industry-standard through-hole (SIP) package. Operating from a 3.0 5.5 V input, these converters are ideal choices for Intermediate Bus Architectures where point of load power delivery is preferred. It provides an extremely tight regulated programmable output voltage of 0.7525 V to 3.63 V. The YNV05T06 converter provides exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished using patent pending circuits, RoHS lead-free solder and lead-solder-exempted packaging, and processing techniques to achieve products are available ultra-high efficiency and excellent thermal Delivers up to 6 A (21.7 W) management. No derating up to 70 C ambient The preclusion of heat sinks minimizes impedance to Industry-standard footprint and pinout system airflow, thus enhancing cooling for both Single-in-Line (SIP) Package: 0.90 x 0.44 x 0.26 upstream and downstream devices. The use of 100% (22.86 x 11.16 x 6.60 mm) automation for assembly, coupled with advanced Weight: 0.08 oz 2.22 g power electronics and thermal design, results in a Synchronous Buck Converter topology product with extremely high reliability.
