The NCV890231 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 NCV890231 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
NCV890231. The NCV890231 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.
