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.

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.
