NCV8856  
Automotive Grade  
Synchronous Buck  
Controller  
The NCV8856 is an adjustable output, synchronous buck controller,  
which drives dual N−channel MOSFETs, ideal for high power  
applications. Average current mode control is employed for very fast  
transient response and tight regulation over wide input voltage and  
output load ranges. The IC incorporates an internal fixed 6.0 V  
low−dropout linear regulator (LDO), which supplies charge to the  
switch mode power supply’s (SMPS) bottom gate driver, limiting the  
power lost to excess gate drive. The IC is designed for operation over  
an input voltage range of 4.5 V to 38 V and is capable of 10 to 1  
voltage conversion at 500 kHz.  
Additional controller features include undervoltage lockout,  
overvoltage shutdown, internal soft−start, low quiescent current sleep  
mode, programmable frequency, SYNC function, average current  
limiting, cycle−by−cycle overcurrent protection and thermal  
shutdown.
