Description

The YEV09T03, non-isolated DC-DC point of load (POL) converter, delivers up to 3A 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 4.5-13.8V input

the POL converter provides an extremely tightly regulated programmable output voltage of 0.59 V to 5.1V. 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 impedance to system airflow, thus enhancing cooling for both upstream and

downstream devices. The use of automation for assembly, coupled with advanced power electronics and thermal

design, results in a product with extremely high reliability.
