DESCRIPTION

The MP2209 is an internally compensated

600kHz fixed frequency PWM synchronous

step-down regulator. With a 3V to 6V bias

supply, MP2209 operates from a 3V to 16V

input and generates an adjustable output

current.

The MP2209 integrates a 80mΩ high-side

switch and a 80mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, it can be stabilized with

ceramic capacitors and small inductors. Fault

condition

protection

includes

short-circuit

protection, cycle-by-cycle current limiting and

thermal shutdown.

The MP2209 is available in small 3mmx4mm

14-lead QFN packages.
