General Description

The RT8058 is a current mode PWM step-down converter.

The chip is ideal for fixed frequency and low ripple applications over full range of load conditions.

Its input voltage range is from 2.6V to 5.5V with a constant 1MHz switching frequency that allows it to adopt tiny, low cost capacitors and inductors with 2mm or less in height making www.DataSheet4U.com it ideal for single-cell Li-lon/polymer battery applications.
