Product Introduction

The controller's equipment UC3827 series provides an integrated control solution for cascading buck and push-pull converters. These converters are known as current Fed or Voltage Fed push-pull converters and are ideal for ideal multi-output and/or high-voltage output applications. In both Fed current Fed and voltage modes, push-pull switches are driven, switched at 50% rated duty cycle and half the buck stage switching frequency. In the current Fed mode, two switches specify the drive, in the circle time, to prevent ringing and voltage stress on the device. In voltage mode, the Fed drives between two switches, and the switches specify the interval time to prevent the energy storage of transformers and capacitors opposite the short circuit, prohibiting the current flowing through these devices.

characteristic

Ideal for multi-output and/or high-voltage output voltage converters
Up to 500 kHz operation
High voltage, high current step-down converter stage floating drive
UC3827-1 The current Fed controller has a push-pull drive overlapping conduction period
The UC3827-2 voltage feed controller features a push-pull driver with a non-overlapping conduction period
Average current mode, peak current mode, or input voltage feedforward voltage mode controls the step-down power stage
Wide bandwidth, low offset, differential current sense amplifier
Precise short-circuit current control
