It’s a state-of-the-art device which is designed to deliver a stable voltage to the load, safely and efficiently. The application field of NCV4276BDT50RKG mainly covers automotive and industrial electronic systems, such as General Motors, Ventilation/Heating/Air-Conditioning systems, Mobile Automation, Lighting and LED driving.

NCV4276BDT50RKG provides typical output currents up to 7.5A. It is able to deliver the desired stability and noise-free output voltage at high frequency currents with excellent thermal performance. In addition, it is also capable of withstanding reverse input voltages of -8V, as well as over-current and over-temperature protection, which makes NCV4276BDT50RKG an ideal voltage regulator for harsh automotive and industrial environments.

The working principle of NCV4276BDT50RKG voltage regulator is similar to many common linear regulators. A pass element, usually a transistor, is inserted between the input and output, and a reference voltage is applied to the gate of the pass element. In order to adjust the output voltage, the reference voltage adjusted by the control/divider network, a feedback loop is formed to control the output voltage. When the output voltage is too low, the control signal increases so that the pass device conducts more current, resulting in an increase of the output voltage. Likewise, when the output voltage is too high, the control signal decreases so that the pass device conducts less current and the output voltage decreases. This way, the reference voltage can accurately control the output voltage.

To sum up, thanks to its ability to withstand reverse input voltages and its superior thermal performance and ruggedness, NCV4276BDT50RKG is an ideal voltage regulator for automotive and industrial electronic systems. Furthermore, the working principle of NCV4276BDT50RKG enables it to accurately adjust the output voltage, satisfying the demanding needs of the applications it serves.
