产品描述

The MP2209 is an internally compensated 600kHz fixed frequency PWM synchronous step-down regulator. With a 3V to 6V bias supply, MP2209 operates from a 3V to 16V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 2A load current. The MP2209 integrates a 80mO high side switch and a 80mO synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, it can be stabilized with ceramic capacitors and small inductors. Fault condition protection includes short-circuit protection, cycle-by-cycle current limiting and thermal shutdown. The MP2209 is available in small 3mmx4mm 14-lead QFN packages.
