Automotive Grade Non-Synchronous Boost Controller NCV8870 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. Features  Peak Current Mode Control with Internal Slope Compensation  1.2 V 2% Reference voltage  Fixed Frequency Operation  Wide Input Voltage Range of 3.
