NCV898031 fiche technique
NCV898031
2 MHz Non-Synchronous
SEPIC/Boost Controller
The NCV898031 is an adjustable output nonsynchronous 2 MHz
SEPIC/boost controller which drives an external Nchannel
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 internallyset softstart, undervoltage
lockout, cyclebycycle current limiting and thermal shutdown.
Additional features include low quiescent current sleep mode and
microprocessor compatible enable pin.
