Converter with Output  
Disconnect  
FEATURES  
DESCRIPTION  
TheLT®8410/LT8410-1areultralowpowerboostconverters  
with integrated power switch, Schottky diode and output  
disconnect circuitry. The parts control power delivery by  
varying both the peak inductor current and switch off-  
time. This control scheme results in low output voltage  
ripple as well as high efficiency over a wide load range.  
The quiescent current is a low 8.5μA, which is further  
reduced to 0μA in shutdown. The internal disconnect  
circuitry allows the output voltage to be blocked from  
the input during shutdown. High value (12.4M/0.4M)  
resistorsareintegratedonchipforoutputvoltagedetection,  
significantly reducing input referred quiescent current.  
The LT8410/-1 also features a comparator built into the
