MP28114DG-LF-P

The MP28114 is a 1.7MHz constant frequency, current mode, ultra-small PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency and eliminates the needs for an external schottky diode. It is ideal for powering portable equipment that runs from a single cell LithiumIon (Li+) battery. The MP28114 can supply 600mA of load current from a 2.5V to 6V input voltage. The output voltage for the MP28114DG can be regulated as low as 0.6V, while the output voltages of the MP28114DG-1.5, MP28114G-1.8, and MP28114DG-3.3 are fixed at 1.5V, 1.8V, and 3.3V, respectively. The MP28114 can also run at 100% duty cycle for low dropout applications. The MP28114 is available in an ultra-small 2x2mm QFN package.
