HIP6004BCB

Special Purpose Regulators Overview

The HIP6004BCB is a Buck and Synchronous-Rectifier PWM Controller designed for high-performance microprocessor power supplies. It integrates control, output adjustment, monitoring, and protection functions to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The device operates from +5V or +12V inputs and features a fast transient response with a high-bandwidth error amplifier. It supports full 0% to 100% duty ratio operation and provides excellent output voltage regulation. The controller includes a TTL-compatible 5-bit Digital-to-Analog converter for precise output voltage selection and utilizes the MOSFET's rDS(ON) for over-current and over-voltage fault monitoring without extra sensing elements.
