MP28115 Description
The MP28115 is an internally pensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP28115 operates from a 2.7V to 6V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 4A load current. The MP28115 integrates a 60mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode.
