MP2209 Datasheet, PDF (1/12 Pages) Monolithic Power Systems – 16V, 2A, 600kHz Synchronous Step-Down Converter

The Future of Analog IC Technology
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
voltage from 0.8V to 0.9xV_IN at up to 2A load
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.
