Monolithic Power Systems MP2212

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 80mΩ high-side switch and an 80mΩ synchronous rectifier for high efficiency without an external Schottkydiode. 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 andthermal 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.
