MP2207
16V, 4A, 1.3MHz Synchronous
Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP2207 is an internally compensated
1.3MHz fixed frequency PWM synchronous
step-down regulator with a 3V to 6V bias supply
(V
CC
). MP2207 operates from a 3V to 16V input
and generates an adjustable output voltage
from 0.8V to 0.9xV
IN
at up to 4A load current.
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.
