NCV8852  
Automotive Grade  
Non-Synchronous Buck  
Controller  
The NCV8852 is an adjustable−output non−synchronous buck  
controller which drives an external P−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 internal soft−start, undervoltage lockout,  
cycle−by−cycle current limit, hiccup−mode overcurrent protection,  
hiccup−mode short−circuit protection.  
Additional features include: programmable switching frequency,  
low quiescent current sleep mode and externally synchronizable  
switching frequency.
