The LT8415 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-channel MOSFETs in each half-bridge are synchronously controlled by a single input pin, and never turn on at the same time in typical applications.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 shutdown. High value (12.4M/0.4M) resistors are integrated on chip for output voltage detection, significantly reducing input referred quiescent current. The LT8415 also features a comparator built into the SHDN pin, overvoltage protection for the CAP, VOUT, OUT1 and OUT2 pins, built in soft start and comes in a tiny 12-pin 3mm × 2mm DFN package.Applications Sensor Power RF Mems Relay Power Low Power Actuator Bias/Control Liquid Lens Driver
