DER-393 - 100 W Slim TV Power Supply

DER-393 - 100 W Low Profile TV Power Supply

Overview

This engineering report describes 12 V, 3.7 A and 24 V, 2.32 A power supplies for LCD TV applications from 90 VAC to 264 VAC. The design can also be used as a generic evaluation board for combining a HiperPFS-3 power factor stage with a LinkSwitch-HP output stage using devices from Power Integration's HiperPFS-3 and LinkSwitch-HP device families. The design is based on the PFS7524L IC for the PFC front-end and uses a LNK6777V in the isolated flyback output stage.
