Synchronous Step-Up DC/DC
Converter with Output Disconnect
The LTC3525-3/LTC3525-3.3/LTC3525-5 are high ef-
ciency synchronous step-up DC/DC converters with
output disconnect that can start up with an input as low
as 1V. They offer a compact, high efciency alternative to
charge pumps in single cell or dual cell alkaline or Li-ion
applications. Only three small external components are
required. The LTC3525 is offered in xed output voltages
of 3V, 3.3V or 5V.
The device includes a 0.5Ω N-channel MOSFET switch
and a 0.8Ω 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 LTC3525 is
available in a tiny 6-pin SC70 package.
