MP28127规格书详情
描述 Description
The MP28127 is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP28127 operates from a 2.7V to 5.5V input and generates an output voltage as low as 0.8V. The MP28127 integrates a high side switch and a synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP28127 based solution delivers a very compact footprint with a minimum component count. The MP28127 is available in a small 3mm x 3mm 10-lead QFN package.
