EVBUM2234DB - NCV890203 Evaluation Board User's Manual
ON Semiconductor
The NCV890203 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 NCV890203 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 NCV890203 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.
