Product Description

The MP2212 is an internally compensated 600KHz fixed frequency PWM synchronous step-down regulator. With a 3V to 6V bias supply (VCC), MP2212 operates from a 3V to 16V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 3A load current. The MP2212 integrates an 80mO high side switch and an 80mO synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, it is stable with a ceramic output capacitor and a small inductor. Fault protection includes hiccup short-circuit protection, cycle-by-cycle current limiting and thermal shutdown. Other features include frequency synchronization input and internal soft-start. The MP2212 is available in small 3mm x 3mm 10-lead QFN and 8-lead SOIC with exposed pad packages.
