The MP2205A is an internally compensated 1.3MHz fixed frequency PWM synchronous step-down regulator with a 3V to 6V bias supply (VCC). MP2205A 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 MP2205A 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 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 MP2205A is available in a small 3x4mm 14-lead QFN packages.
