RT8058A
1.
2MHz, 2A, High Efficiency PWM Step-Down DC/DC Converter
General Description
The RT8058A 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 1.
2MHz switching frequency that allows it to adopt tiny, low cost capacitors and inductors with 2mm or less in height making it ideal for single-cell Li-lon/polymer battery applications.
The low on resistance internal MOSFET can achieve high efficiency without the need of external
schottky diodes in wide operating ranges and the output voltage is adjustable from 0.
6V to 5V that can provide up ...
