NCV8873

Automotive Grade

Non-Synchronous Boost

Controller

The NCV8873 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.
