DESCRIPTIO  
FEATURES  
The LTC®3525-3/LTC3525-3.3/LTC3525-5 are high ef-  
ficiency 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 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.  
■
Up to 95% Efficiency  
■
Output Disconnect and Inrush Current Limit  
■
Fixed Output Voltages of 3V, 3.3V or 5V  
■
Delivers 65mA at 3V from a 1V Input  
■
Delivers 60mA at 3.3V from a 1V Input,  
or 140mA at 3.3V from a 1.8V Input  
■
Delivers 175mA at 5V from a 3V Input  
Burst Mode® Operation: I = 7µA  
■
Q
■
Only Three External Components  
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.
