HT77231 - Synchronous Buck Converter

Datasheet Summary

Description

The HT77231 is a 3.5A, step-down, buck converter with minimum external components and low shutdown current.

The device delivers a fast transient response with both low ESR (polymer) and ultra-low ESR (ceramic) output capacitors, and no external compensation is needed.

Features

  • 3.5A converter with 100mΩ and 60mΩ FETs Fast transient response with minimum external components Input voltage range: 4.0V~28V Output voltage range: 0.6 V~13V Pulse skip mode to keep high efficiency in light load 600kHz switching frequency Shutdown current:.
