LT3464  
Micropower Boost  
Converter with Schottky and  
Output Disconnect in ThinSOT™  
U
DESCRIPTIO  
FEATURES  
The LT®3464 is a micropower step-up DC/DC converter  
with integrated Schottky diode and output disconnect  
packaged in an 8-lead low profile (1mm) SOT-23. The  
small package size, high level of integration, and the use  
of tiny SMT components yield a solution size of less than  
40mm2. The LT3464 has a typical current limit of 115mA  
as well as fast switching speed to allow the use of a chip  
inductor and small ceramic capacitors. The internal PNP  
disconnects the output load from the input during shut-  
down, and also provides output short-circuit protection.  
An auxiliary reference input allows the user to override the  
internal 1.25V feedback reference with any lower value,  
allowing full control of the output voltage during opera-  
tion. This device features a low 25µA quiescent current,  
which is further reduced to less than 0.5µA in shutdown.  
A current limited fixed off-time control scheme conserves  
operating current, resulting in high efficiency over a broad  
range of operating current. The rugged 36V switch and  
output disconnect circuitry allow outputs up to 34V to be  
easily generated in a simple boost topology.
