Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.




Description

This integrated Switching LED Driver NUD4023 provides a regulated dc current to an LED powered from a standard automotive 12 V system. NUD4023 is a low cost switching device which utilizes a minimal of external components that can be used to power high intensity LEDs for a number of applications.

The NUD4021 is recommended for currents of 50 mA to 400 mA, while the NUD4022/NUD4023 is recommended for currents of 300 mA to 2.0 A.
