MP28128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 MP28128 is a 1.5MHz fixed frequency PWM synchronous step-down regulator with internal compensation. MP28128 operates from a 2.7V to 6V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 2.5A load current. The MP28128 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 MP28128 based solution delivers a very compact footprint with a minimum component count. Fault condition protection includes hiccup short-circuit protection, cycle-by-cycle current limiting and thermal shutdown. Other features include frequency synchronization input, internal soft-start and power good output. The MP28128 is available in a small 3x3mm 10-lead QFN package.
