NCV887001D1R2G Datasheet PDF - ON Semiconductor

●The NCV8870 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, hiccup−mode short−circuit protection and thermal shutdown. Additional features include low quiescent current sleep mode and externally−synchronizable switching frequency.
