Datasheet: 2 MHz Automotive Grade Non-Synchronous Boost Controller
Rev. 2 (232kB)
Product Overview
»View Material Composition
» Product Change Notification
The NCV898032 is an adjustable output non−synchronous 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 input pin.
