Description

The LT8410/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) resistors are integrated on chip for output voltage detection, significantly reducing input referred quiescent current. The LT8410/LT8410-1 also features a comparator built into theSHDNpin, over voltage protection for the CAP and VOUTpins, built in soft-start and comes in a tiny 8-pin 2mm × 2mm DFN package.ApplicationsSensor PowerRF Mems Relay PowerGeneral Purpose Bias
