IR3827 Datasheet Synchronous Buck Regulator

Manufacturer: International Rectifier (now Infineon)

Overview: 6A Highly Integrated SupIRBuckTM SingleInput Voltage, Synchronous Buck Regulator.

General Description

The IR3827 SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator.

The onboard PWM controller and MOSFETs make IR3827 a space-efficient solution, providing accurate power delivery for low output voltage applications.

IR3827 is a versatile regulator which offers programmable switching frequency and internally set current limit while operating in wide range of input and output voltage conditions.

Key Features

  • Single input voltage range from 5V to 21V.
  • Wide input voltage range from 1.0V to 21V with external VCC bias voltage.
  • Output voltage range from 0.6V to 0.86% PVin.
  • Enhanced line/load regulation with feedforward.
  • Programmable switching frequency up to 1.2MHz.
  • Three user selectable soft-start time.
  • User selectable LDO output voltage.
  • Enable input with voltage monitoring capability.
  • Thermally compensated current limit.
