LV2843DDCR

The LV284 is a PWM DC/DC buck (step - down) regulator. With a wide input range from 4 V to 40V, the device is designed for a wide range of applications from industrial to automotive. An ultralow, 1 - μA shutdown current prolongs battery life. Operating frequency is fixed at 0.7 MHz allowing the use of small external components while still being able to have low output ripple voltage. Soft - start and compensation circuits are implemented internally, and these allow the device to be used with minimum external components. The LV284 is optimized for up to 1 - A load current. The device has a 0.765 - V nominal feedback voltage. The device has built - in protection features such as pulse - by - pulse current limit, thermal sensing and shutdown due to excessive power dissipation. The LV284 is available in a low profile TSOT - 6L package.
