The NCV898031 is an adjustable output non-synchronous 2 MHz SEPIC/boost controller which drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver.Protection features include internally-set soft-start, undervoltage lockout, cycle-by-cycle current limiting and thermal shutdown.Additional features include low quiescent current sleep mode and microprocessor compatible enable pin.
