  • Product introduction

The UCC3583 is synchronized with the output accuracy of the secondary side and the auxiliary output post-regulation regulation of multiple power supplies. It contains an advanced pulse-width modulator that generates the gate drive signal of a rectifier diode switch in series with a power FET. The power switch delay of voting from the secondary power pulse is the lead of adjusting the output voltage. The UCC3583 contains a ramp generator dependent on the second pulse power, voltage error amplifier, current error amplifier, PWM comparator and associated logic, a gate driver, an accurate reference, and protection circuitry.

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

UC3864 TI 08+ 16PDIP The IC-1868 series of UC1861 is best suited for the control of zero-current switching and zero-voltage switching quasi-resonant converters. This differs from UVLO's threshold and output selection to the members of the various combinations of device family results. In addition, a single-pulse steering logic configuration scheme is configured for either zero-current systems at the time (UC1865-1868) or zero-voltage switching applications at off-time (UC1861-1864).
