Texas Instruments UC2827-1 Buck Current/Voltage Fed Push-Pull PWM Controllers UC2827DW-1

The UC2827-1 is a Buck Current/Voltage Fed Push-Pull PWM Controller designed by Texas Instruments. It operates at a maximum frequency of 500 kHz and is suitable for applications requiring multiple outputs or high voltage outputs. The device features both current-fed and voltage-fed modes, with push-pull drivers that can be configured for overlapping or non-overlapping conduction periods, depending on the specific model. The controller includes advanced features such as average current mode control, peak current mode control, and voltage mode control with input voltage feedforward. It also incorporates a differential current sense amplifier with low offset and high bandwidth, as well as soft start circuitry and precise short circuit current control. The UC2827-1 supports input voltages up to 72 VDC and provides comprehensive protection and PWM control functions for the buck converter. This device is available in a 24-pin SOIC package and operates over a temperature range of -40°C to 85°C, making it suitable for a variety of industrial applications.
