NCV898031

2 MHz Non-Synchronous

SEPIC/Boost Controller

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.
