Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YEV09T03, non-isolated DC-DC point of load (POL) converter, delivers up to 3 A of output current in an industry-standard single-in-line (SIP) through-hole package. The YEV09T03 POL converter is an ideal choice for Intermediate Bus Architectures where point of load conversion is a requirement. Operating from a 4.5 V to 13.8 V input the POL converter provides an extremely tightly regulated programmable output voltage of 0.59 V to 5.1 V. The POL converter offers exceptional thermal performance, even in high temperature environments with minimal airflow. This performance is accomplished through the use of advanced circuit solutions, packaging and processing techniques. The resulting design possesses ultra-high efficiency, excellent thermal management, and a slim body profile that minimizes RoHS lead free and lead-solder-exempt products impedance to system airflow, thus enhancing cooling for both are available upstream and downstream devices. Wide operating temperature range: 0 to 70 C The use of automation for assembly, coupled with advanced optional to a range of -40 to 85 C power electronics and thermal design, results in a product with High efficiency synchronous buck topology extremely high reliability. Low noise fixed frequency operation Wide input voltage range: 4.5V13.8V High continuous output current: 3A Programmable output voltage range: 0.59V5.1V Low voltage, high density systems with Intermediate Overcurrent, and short circuit protections with Bus Architectures (IBA) Point-of-load regulators for high performance DSP, automatic restart FPGA, ASIC, and microprocessors Enable input Desktops, servers, and portable computing Start up into prebiased load Broadband, networking, optical, and communications No minimum load requirements systems High MTBF of 67 million hours Industry standard size through-hole single-in-line package and pinout: 0.41 x 0.65 x 0.40 inches (10.4 x 16.51 x 10.16 mm) One part that covers many applications UL94 V-0 flammability rating Reduces board space, system cost and complexity, Safety approved to UL/CSA 62368-1 and and time to market EN/IEC 62368-1 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.
