The YEV09T06, non-isolated DC-DC point of load (POL) converter, delivers up to 6A of output current in an
industry-standard single-in-line (SIP) through-hole package. The YEV09T06 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 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.
