Buck Switching Regulator - Automotive, RESET 2.0 A, 2 MHz
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.
