Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YEV09T20-0 non- isolated DC-DC point of load (POL) converter delivers up to 20A of output current in an industry-standard single-in-line (SIP) through-hole package. The YEV09T20-0 POL converter is an ideal choice for Intermediate Bus Architectures where point of load conversion is a requirement. Operating from a 4.5-13.8V input the POL converter provides an extremely tightly regulated programmable output voltage of 0.59V to 5.1V. The POL converter offers exceptional thermal performance, even in high temperature environments with minimal airflow. This performance is accomplished RoHS lead free and lead-solder-exempt products through the use of advanced circuit solutions, packaging and are available processing techniques. The resulting design possesses High efficiency synchronous buck topology ultra-high efficiency, excellent thermal management, and a slim body profile that minimizes impedance to system airflow, Low noise fixed frequency operation thus enhancing cooling for both upstream and downstream Wide input voltage range: 4.5V13.8V devices. The use of automation for assembly, coupled with High continuous output current: 20A advanced power electronics and thermal design, results in a Programmable output voltage range: 0.59V5.1V product with extremely high reliability. Overcurrent, and output overvoltage protections with automatic restart Remote differential output voltage sense Power Good signal Low voltage, high density systems with Enable input Intermediate Bus Architectures (IBA) Start up into prebiased load Point-of-load regulators for high performance DSP, FPGA, ASIC, and microprocessors No minimum load requirements Desktops, servers, and portable computing High MTBF of 64 million hours Broadband, networking, optical, and Industry standard size through-hole single-in-line communications systems package and pinout: 1.45 x 0.61 x 0.425 inches (36.8 x 15.5 x 6.08 mm) Wide operating temperature range: 0 to 70C UL94 V-0 flammability rating One part that covers many applications Safety approved to UL/CSA 62368-1 and Reduces board space, system cost and EN/IEC 62368-1 complexity, and time to market 2 YEV09T20 DC-DC Converter 1. ABSOLUTE MAXIMUM RATINGS Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long-term reliability, and cause permanent damage to the converter.
