DESCRIPTION

The MP2207 is an internally compensated

1.3MHz fixed frequency PWM synchronous

step-down regulator with a 3V to 6V bias supply

and generates an adjustable output voltage

The MP2207 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 MP2207 is available in small 3mm x 3mm

10-lead QFN and SOIC8E packages.
