Product Preview  
NCV881935  
www.onsemi.com  
The NCV881935 is an adjustable 410 kHz fixed−frequency low  
quiescent current buck controller with spread spectrum that operates  
up to 38 V (typical). It may be synchronized to a clock or to separate  
NCV881935. Peak current mode control is employed for fast transient  
response and tight regulation over wide input voltage and output load  
ranges. Feedback compensation is internal to the device, permitting  
design simplification. The NCV881935 is capable of converting from  
an automotive input voltage range of 3.5 V (4.5 V during startup) to  
18 V at a constant base switching frequency. Under load dump  
conditions up to 45 V the regulator shuts down. A high voltage bias  
regulator with automatic switchover to an external 5 V bias supply is  
used for improved efficiency. Several protection features such as  
UVLO, current limit, short circuit protection, and thermal shutdown  
are provided. High switching frequency produces low output voltage  
ripple even when using small inductor values and an all−ceramic  
output filter capacitor, forming a space−efficient switching solution.
