Monolithic Power Systems MP38115

Description

The MP38115 is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP38115 operates from a 1.1V to 5.5V input and generates an output voltage as low as 0.8V.The MP38115 integrates a 60mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP38115 basedsolution delivers a very compact footprint with a minimum component count.The MP38115 is available in a small 3mm x 3mm 10-lead QFN package.
