Technical

Specification

PQ60018ETL45

is a next-generation, board-mountable, isolated, fixed

switching frequency DC/DC converter that uses synchronous

rectification to achieve extremely high conversion efficiency.

The power dissipated by the converter is so low that

a heatsink is not required, which saves cost, weight,

height, and application effort. All of the power and

control components are mounted to the multi-layer PCB

substrate with high-yield surface mount technology. Since

the PowerQor converter has no explicit thermal interfaces,

it is extremely reliable. RoHS Compliant (see page 14).
