400mA Micropower
Synchronous Step-Up DC/DC
Converter with Pass Through Mode
The LTC3525D-3.3 is a high efficiency synchronous step-
up DC/DC converter that can start up with an input as low
as 0.85V. It offers 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 LTC3525D features a fixed output voltage
of 3.3V. In shutdown, VOUT is connected to VIN through
the inductor.
The device includes a 0.5
Ω N-channel MOSFET switch
and a 0.8
Ω P-channel synchronous rectifier. Peak switch
current ranges from 150mA to 400mA, depending on
load, providing enhanced efficiency. Quiescent current
is an ultralow 7A, maximizing battery life in portable
applications.
Other features include anti-ringing control and thermal
shutdown. The LTC3525D is available in a tiny 6-pin SC70
package.
