DESCRIPTION

The MP2212 is an internally compensated

600kHz fixed frequency PWM synchronous

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

16V input and generates an adjustable output

current.

The MP2212 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

ceramic output 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 input and internal

soft-start.

The MP2212 is available in small 3mm x 3mm

10-lead QFN and 8-lead SOIC with exposed

pad packages.
