MP1522
25V Step-Up Converter
in a SOT23-5 Package
The Future of Analog IC Technology
DESCRIPTION
The MP1522 is a step up converter that
generates up to a 25V output voltage from a
2.7V to 25V input. It uses a current limited
Variable Frequency control algorithm to
optimize efficiency and minimize external
component size and cost. The internal 0.5Ω
N-Channel MOSFET switch can withstand up to
28V allowing the MP1522 to produce high
output voltage with high efficiency.
The MP1522 includes input under voltage and
over temperature protection. The MP1522 is
available in tiny 5-pin SOT23 packages.
