LT8410-1

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 offtime. This control scheme results in low output voltage ripple as well as high effi ciency over a wide load range. The quiescent current of LT8410-1 is a low 8.5A, which is further reduced to 0A in shutdown. The internal disconnect circuitry allows the output voltage to be blocked from the input during shutdown. High value (12.4M/0.4M) resistors are integrated on chip for output voltage detection, signifi cantly reducing input referred quiescent current. The LT8410/-1 also features a comparator built into the SHDN pin, over voltage protection for the CAP and V_OUT pins, built in soft-start and comes in a tiny 8-pin 2mm * 2mm DFN package.
