2.0 A, 2 MHz Automotive

Buck Switching Regulator

with Programmable Spread

Spectrum and Adjustable

RSTB

www.onsemi.com

The NCV890204 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 NCV890204 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.

The NCV890204 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.
