DescripTion
The LTC
®
3525-3/LTC3525-3.3/LTC3525-5 are high efficiency
synchronous step-up DC/DC converters with output discon-
nect that can start up with an input as low as 0.85V. They
offer a compact, high efficiency 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 fixed 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 rectifier. Peak switch current
ranges from 150mA to 400mA, depending on load, providing
enhanced efficiency. Quiescent current is an ultralow 7µA,
maximizing battery life in portable applications.
Other features include <1µA shutdown current, anti-
ringing control and thermal shutdown. The LTC3525 is
available in a tiny 6-Lead SC70 package.
