Description

The MP2207 is an internally compensated 1.3MHz fixed frequency PWM synchronous step-down regulator with a 3V to 6V bias supply (VCC). MP2207 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 MP2207 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 output ceramic capacitor and a small inductor. Fault protection includes hiccup short-circuit protection, cycle-by-cycle current limiting andthermal shutdown. Other features include frequency synchronization and internal softstart.The MP2207 is available in small 3mm x 3mm 10-lead QFN and SOIC8E packages.
