Synchronous Step-Up DC/DC
Converter with Output Disconnect
The LTC3525L-3 is a high efciency synchronous step-
up DC/DC converter with output disconnect that can
start up with an input as low as 0.7V. It offers a compact,
high efciency alternative to charge pumps in single
cell or dual cell alkaline applications. Only three small
external components are required. The LTC3525L-3
generates a xed 3V output voltage.
The device includes a 0.5
N-channel MOSFET switch
and a 0.85 P-channel synchronous rectier. Peak switch
current ranges from 150mA to 400mA, depending on
load, providing enhanced efciency. Quiescent current
is an ultralow 7A, maximizing battery life in portable
applications.
Other features include <1A shutdown current, anti-
ringing control and thermal shutdown. The LTC3525L-3
is available in a tiny 6-pin SC70 package.
