UCC2583

• Product Introduction

The UCC3583 is the output accuracy of the synchronized secondary side of the auxiliary output of multiple power supplies after regulating the voltage regulation. It contains an advanced pulse-width modulator that generates a gate drive signal for a rectifier diode switch connected in series with a power FET tube. The power switching delay of the vote regulates the lead of the output voltage from the secondary power pulse. The UCC3583 contains a ramp generator subordinate to the secondary pulse power, a voltage error amplifier, a current error amplifier, a PWM comparator and associated logic, a gate driver, an accurate reference, and protection circuit.

Synchronous pulses triggered by ramp discharge and terminated gate drive signals are typically generated from the secondary voltage drop edge of the transformer.
