The document describes the UCC1583, UCC2583, and UCC3583 as synchronizable secondary side post regulators designed for precision regulation of auxiliary outputs in multiple output power supplies. These controllers utilize a leading edge pulse width modulator to generate gate drive signals for FET power switches connected in series with rectifying diodes.
