DESCRIPTION
The MP3115 is a synchronous, fixed frequency,
current mode step-up converter with output-to-
input disconnect optimized to boost a single AA
Alkaline battery to 2.5V or 3.3V.
It can startup from an input voltage as low as
0.950V and provide in-rush current limiting as
well as output short circuit protection. The
integrated P-Channel synchronous rectified
switch provides improved efficiency and
eliminates an external schottky diode. The
output disconnect feature allows the output to be
completely discharged, thus allowing the part to
draw less than 1µA of current in shutdown mode.
The 1.3MHz switching frequency allows for the
use of smaller external components and the
internal compensation and soft-start minimize
the external component count, all helping to
produce a compact solution for a wide range of
load current.
The MP3115 regulates the output voltage up to
4.0V or 3.3V at 200mA from a single cell AA
battery, without the use of an external Schottky
diode.
The MP3115 is offered in a SOT23-6 package.
