MP38115数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 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 60mO high side switch and a 60mO synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP38115 based solution delivers a very compact footprint with a minimum component count. The MP38115 is available in a small 3x3mm 10-lead QFN package.
