NCV890104  
1.2 A, 2 MHz Automotive  
Buck Switching Regulator  
with Programmable Spread  
Spectrum and Adjustable  
RSTB  
www.onsemi.com  
The NCV890104 is a fixed−frequency, monolithic, Buck switching  
regulator intended for Automotive, battery−connected applications  
that must operate with up to a 36 V input supply. The regulator is  
suitable for systems with low noise and small form factor  
requirements often encountered in automotive driver information  
systems. The NCV890104 is capable of converting the typical 4.5 V to  
18 V automotive input voltage range to outputs as low as 3.3 V at  
a constant switching frequency above the sensitive AM band,  
eliminating the need for costly filters and EMI countermeasures.  
A Reset pin signals when the output is in regulation, and a pin is  
provided to adjust the delay before the RSTB signal goes high.  
The NCV890104 also provides several protection features expected in  
Automotive power supply systems such as current limit, short circuit  
protection, and thermal shutdown. In addition, the 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 regulator solution.
