1.2 A, 2 MHz Automotive
Buck Switching Regulator
The NCV890130 is a fixedfrequency, monolithic, Buck switching
regulator intended for Automotive, batteryconnected 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 NCV890130 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
NCV890130 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 allceramic output filter capacitor forming a
spaceefficient switching regulator solution.

Description
1 VIN Input voltage from battery. Place an input filter capacitor in close proximity to this pin.
2
DRV
Output voltage to provide a regulated voltage to the Power Switch gate driver.
3
GND
Battery return, and output voltage ground reference.
4 EN This TTL compatible Enable input allows the direct connection of Battery as the enable signal. Grounding
this input stops switching and reduces quiescent current draw to a minimum.
5
COMP
Error Amplifier output, for tailoring transient response with external compensation components.
6 FB Feedback input pin to program output voltage, and detect precharged or shorted output conditions.
7 BST Bootstrap input provides drive voltage higher than VIN to the Nchannel Power Switch for optimum
switch RDS(on) and highest efficiency.
8 SW Switching node of the Regulator. Connect the output inductor and cathode of the freewheeling diode to
this pin.
