MP2205

Pinout




Description

The MP2205 is an internally compensated 1.3MHz fixed frequency PWM synchronous step-down regulator with a 3V to 6V bias supply (VCC). MP2205 operates from a 3V to 16V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 2.5A load current. The MP2205 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 soft-start.The MP2205 is available in a small 3mm x 4mm 14-lead QFN packages.
