UCC1583 - Unitrode

UCC1583 (UCC1583 - UCC3583) Switch Mode Secondary Side Post Regulator

The UCC3583 is a synchronizable secondary side post regulator for precision regulation of the auxiliary outputs of multiple output power supplies. It contains a leading edge pulse width modulator, which generates the gate drive signal for a FET power switch connected in series with the rectifying diode. The turn-on of the power switch is delayed from the lea.
