UC2827-1, UC2827-2 UC3827-1, UC3827-2 www.ti.com SLUS365D * APRIL 1999 * REVISED APRIL 2011 BUCK CURRENT/VOLTAGE FED PUSH-PULL PWM C.
The UC3827 family of controller devices provides an integrated control solution for cascaded buck and push-pull converters.
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
