Monolithic Power Systems MP2214

Description

The MP2214 is an internally compensated 600kHz fixed frequency PWM synchronous step-down regulator with a 3V to 6V bias supply (VCC). MP2214 operates from a 3V to 16V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 4A load current.The MP2214 integrates an 80mΩ high-side switch and an 80mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, it is stable with a output ceramic 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 and internal softstart.The MP2214 is available in small 3mm x 4mm 14-lead QFN and 8-lead SOIC with exposed pad packages.
