MP2107 Datasheet | Monolithic Power Systems

DESCRIPTION The MP2107 is an internally pensated 1.5MHz fixed-frequency PWM synchronous step-down regulator. MP2107 operates from a 2.7V to 6V input and generates an output voltage as low as 0.8V. The MP2107 integrates a 80mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal pensation, the MP2107 based solution delivers a very pact footprint with a minimum ponent 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.
