UCC3583 (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.

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 Current Limiting Loop DESCRIPTION The UCC3583 is a synchronizable secondary side post regulator for precision regulation of the auxiliary outputs of multiple output power.
