Product Summary

The RT8058GQW 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 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 to 2A load current. TheRT8058GQW operates at 100% duty cycle for low dropout operation that extends battery life in portable devices. The applications of the RT8058GQW include Portable Instruments, Microprocessors and DSP Core supplies, Cellular Telephones, Wireless and DSL Modems, Digital Cameras, PC Cards.
