UC2827-2 Datasheet | Texas Instruments

FEATURES - Ideal for Multiple Output and/or High Voltage Output Voltage Converters - Up to 500 k Hz Operation - High Voltage, High Current Floating Driver for Buck Converter Stage - UC3827-1 Current Fed Controller has Push-Pull Drivers with Overlapping Conduction Periods - UC3827-2 Voltage Fed Controller has Push-Pull Drivers with Nonoverlapping Conduction Periods - Average Current Mode, Peak Current Mode or Voltage Mode with Input Voltage Feedforward Control for Buck Power Stage - Wide Bandwidth, Low Offset, Differential Current Sense Amplifier - Precise Short Circuit Current Control DESCRIPTION The UC3827 family of controller devices provides an integrated control solution for cascaded buck and push-pull converters. These converters are known as current fed or voltage fed push-pull converters and are ideally suited for multiple output and/or high voltage output applications. In both current fed and voltage fed modes, the push-pull switches are driven at 50% nominal duty cycles and...
