Buck Converter

Features

General Description

The uP1741P is a high performance synchronous buck Wide Input Voltage Range from 4.5V to 26V

converter. The synchronous buck of the uP1741P adopts

uPI proprietary robust constant on-time (RCOT^TM) PWM

Fast Load Transient Response

Output Current up to 8A

scheme that features easy-to-use, low external component
