DATA SHEET www.onsemi.com Automotive Grade Non-Synchronous Boost Controller NCV8873 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. 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 externally−synchronizable switching frequency. Features  Peak Current Mode Control with Internal Slope Compensation  0.2 V $3% Reference Voltage for Constant Current Loads  Fixed Frequency Operation  Wide Input Voltage Range of 3.
