Beschreibung

This reference design supplies two non-isolated and two isolated output voltages. It references a regulated 3.3-V/0.25-A and an unregulated 12-V/0.05-A output on the primary-side, and it isolates two 12-V/0.025-A unregulated outputs. The design operates over an input voltage range of 7 V to 45 V and offers minimal voltage ringing on the FET for lower stress and reduced EMI.

Eigenschaften

SEPIC topology eliminates FET voltage ringing for reduced stress and lower EMIFour-output single-ended primary-inductor converter (SEPIC) from single transformer provides excellent cross regulationFull load efficiency greater than 80% from 12-V and 24-V inputCompact size (30 mm x 40 mm) minimizes required PCB area

Typische Anwendungen
