NCV890104
1.2 A, 2 MHz Automotive
Buck Switching Regulator
with Programmable Spread
Spectrum and Adjustable
RSTB
The NCV890104 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 NCV890104 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 NCV890104 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.
