The LT ? 8410/LT8410-1 are ultralow power boost converters
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) resis-
tors are integrated on chip for output voltage detection,
significantly reducing input referred quiescent current. The
LT8410/ LT8410-1 also features a comparator built into the
SHDN pin, overvoltage protection for the CAP and V OUT
pins, built in soft-start and comes in a tiny 8-pin 2mm ×
2mm DFN package.
