4A, 6V Synchronous, Step-Down Switching Regulator



The MP2107 is an internally compensated 1.5MHz fixed-frequency PWM synchronous step-down regulator. MP2107 operates from a 2.7V to 5.5V input and generates an output voltage as low as 0.8V. The MP2107 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 MP2107 based solution delivers a very compact footprint with a minimum component count. The MP2107 is available in a small 3mm x 3mm 10-pin QFN package and the MP2107A is available in an 8-pin SOIC package with an exposed pad.
