Datasheet: UC2827-1-etcTI.pdf
Description: BUCK CURRENT/VOLTAGE FED PUSH-PULL PWM CONTROLLERS

Features

* 1
* Ideal for Multiple Output and/or High Voltage Output Voltage Converters
* Up to 500 kHz Operation
* High Voltage, High Current Floating Driver for Buck Converter Stage
* UC3827-1 Current Fed Controller has Push-Pull Drivers with Overlapping Conduction Periods

Applications

* In both current fed and voltage fed modes, the push-pull switches are driven at 50% nominal duty cycles and at one half the switching frequency of the buck stage. In the current fed mode, the two switches are driven with a specified over-lap period to prevent ringing and voltage stress on the devic
