HT7702 - Synchronous Buck Converter

Description

The HT7702 is a 2A, synchronous buck converter with minimum external components and low shutdown current.

The device operates in PWM mode with typical 1.5MHz switching frequency at medium to heavy loads.

At light load, the device operates in power save mode to keep high efficiency.

Features

  • 2A converter with 150mΩ and 100mΩ FETs Input voltage range: 2.5V~5.5V Output voltage range: 0.6 V~VIN Power save mode to keep high efficiency in light load 100% duty cycle for low dropout 30uA Quiescent Current 1.5MHz typical switching frequency Shutdown current:.
