General Description

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 leading edge of the secondary power pulse to regulate the output voltage.

Key Features

  • Precision Secondary Side Post Regulation for Multiple Output Power Supplies.
  • Useful for Both Single Ended and Center Tapped Secondary Circuits.
  • Ideal Replacement for Complex Magnetic Amplifier Regulated Circuits.
  • Leading Edge Modulation.
  • Does Not Require Gate Drive Transformer.
  • High Frequency (>500kHz) Operation.
  • Applicable for Wide Range of Output Voltages.
  • High Current Gate Driver (0.5A Sink/1.5A Source).
  • Average.
