Automotive Grade

Non-Synchronous Boost

Controller

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.
