LT3495/LT3495B/  
LT3495-1/LT3495B-1  
650mA/350mA Micropower  
Low Noise Boost Converter  
with Output Disconnect  
FEATURES  
DESCRIPTION  
TheLT®3495/LT3495B/LT3495-1/LT3495B-1arelownoise  
boost converters with integrated power switch, feedback  
resistor and output disconnect circuitry. The parts control  
power delivery by varying both the peak inductor current  
and switch off-time. This novel* control scheme results  
in low output voltage ripple as well as high efficiency  
over a wide load range. For the LT3495/LT3495-1, the  
off-time of the switch is not allowed to exceed a fixed  
level, guaranteeing the switching frequency stays above  
the audio band for the entire load range. The parts feature  
a high performance NPN power switch with a 650mA  
and 350mA current limit for the LT3495/LT3495B and  
LT3495-1/LT3495B-1 respectively. The quiescent current  
is a low 60µA, which is further reduced to less than 0.1µA  
in shutdown. The internal disconnect circuitry allows the  
output voltage to be isolated from the input during shut-  
down. An auxiliary reference input (CTRL pin) overrides  
the internal 1.235V feedback reference with any lower  
value allowing full control of the output voltage during  
operation. TheLT3495seriesareavailableinatiny10-lead
