Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV12T05 non-isolated DC-DC converters deliver up to 5 A of output current in an industry-standard through-hole (SIP) package. The YNV12T05 converters operate from a 9.6 VDC14 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 0.7525 to 5.5 VDC. The YNV12T05 converters provide exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished using circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management, and a very sleek body profile. RoHS lead-free solder and lead-solder-exempted products are available The sleek body profile and the preclusion of heat Delivers up to 5 A (27.5 W) sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and Industry-standard footprint and pinout downstream devices. The use of 100% Single-in-Line (SIP) Package: automation for assembly, coupled with 0.90 x 0.44 x 0.240 advanced power electronics and thermal design, 22.86 mm x 11.16 mm x 6.10 mm results in a product with extremely high reliability.
