The Future of Analog IC Technology
The MP1541 is a 5-pin thin SOT23 current
mode step up converter intended for small, low
power applications. The MP1541 switches at
1.3MHz and allows the use of tiny, low cost
capacitors and inductors 2mm or less in height.
Internal soft start results in small inrush current
and extends battery life. The MP1541 operates
from an input voltage as low as 2.5V and can
generate 12V at up to 300mA from a 5V supply.
The MP1541 includes under-voltage lockout,
current limiting, and thermal overload protection
to prevent damage in the event of an output
overload. The MP1541 is available in a small
5-pin TSOT23 package.
