NCV890131  
1.2 A, 2 MHz Automotive  
Buck Switching Regulator  
The NCV890131 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 NCV890131 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. Two  
pins are provided to synchronize switching to a clock, or to another  
NCV890131. The NCV890131 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.
