Converter with Dual  
Half-Bridge Switches  
FEATURES  
DESCRIPTION  
The LT®8415 is an ultralow power boost converter with  
two integrated complementary MOSFET half-bridges  
(N- and P-channel), integrated power switch, Schottky  
diode and output disconnect circuitry. The N-channel and  
P-channelMOSFETsineachhalf-bridgearesynchronously  
controlled by a single input pin, and never turn on at the  
same time in typical applications.

Wide Input Range: 2.5V to 16V  
The boost regulator controls 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 10.5μA, which is further reduced to 0μA  
in shutdown. The internal disconnect circuitry allows the  
output voltage to be blocked from the input during shut-  
down. High value (12.4M/0.4M) resistors are integrated  
onchipforoutputvoltagedetection,significantlyreducing
