The RT8058 is a current mode PWM step-down converter.The chip is ideal for fixed frequency and low rippleapplications over full range of load conditions. Its inputvoltage range is from 2.6V to 5.5V with a constant 1MHzswitching frequency that allows it to adopt tiny, low costcapacitors and inductors with 2mm or less in height makingit ideal for single-cell Li-lon/polymer battery applications.The low on resistance internal MOSFET can achieve highefficiency without the need of external schottky diodes inwide operating ranges and the output voltage is adjustablefrom 0.6V to 5V that can provide up to 2A load current.The RT8058 operates at 100% duty cycle for low dropoutoperation that extends battery life in portable devices.The RT8058 is available in a WQFN-16L 3x3 package.
