4A, 6V Synchronous Step-Down Switching Regulator

Overview

TopologyBuck Converter
Input voltage2.7-5.5 V
Output 11.8 V / 4 A
IC revision1.1

Description

The MP2107 is an internally compensated 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 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.
