The Future of Analog IC Technology
DESCRIPTION
The MP28115 is an internally compensated
1.5MHz fixed frequency PWM synchronous
step-down regulator. MP28115 operates from a
2.7V to 6V input and generates an adjustable
output voltage from 0.8V to 0.9xVIN at up to 4A
load current.
The MP28115 integrates a 60mhigh-side
switch and a 60msynchronous rectifier for
high efficiency without an external Schottky
diode. With peak current mode control and
internal compensation, the MP28115 based
solution achieves minimum footprint and
component count. Fault condition protection
includes Hiccup short-circuit protection, cycle-
by-cycle current limiting and thermal shutdown.
Other
features
include
frequency
synchronization input, internal soft-start and
power good output.
The MP28115 is available in a small 3mm x
3mm 10-lead QFN package.
