Description
The QLS25 is a new series of cost-effective, high-density single output DC-DC converters providing onboard
conversion of standard telecom and datacom input voltages into isolated low voltage outputs in a through-hole
mounting package. High efficiencies and a patent-pending board design significantly improve thermal
characteristics by evening out hot spots and enhance product reliability.
