MP2212
16V, 3A, 600kHz Synchronous
Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP2212 is an internally compensated
600kHz fixed frequency PWM synchronous
step-down regulator. With a 3V to 6V bias
supply (V
CC
), MP2212 operates from a 3V to
16V input and generates an adjustable output
voltage from 0.8V to 0.9xV
IN
at up to 3A load
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.
