The NCV78M12BDTRKG is a linear voltage regulator integrated circuit (IC) from the ON Semiconductor family. It is part of the PMIC (Power Management IC) product range and is used for various types of voltage regulation applications.The device is a synchronous buck step-down regulator with a maximum output current of 12A and a wide input voltage range of up to 100V. It has integrated protection features such as over-temperature, over-current, short-circuit and under-voltage lockouts.The device is suitable for various types of applications including but not limited to automotive, industrial, communication and consumer electronics. It can be used in automotive lighting applications like LED headlights, LED rear lights and RGB LED applications. In industrial applications, the device can be used in DC-DC converters, UPS systems, motor speed control, DC motor drives and motor control systems.The NCV78M12BDTRKG also has a buck-boost topology, making it suitable for applications requiring a negative output voltage. It also has constant frequency operation with a minimum on-time of 500ns.The working principle of the linear voltage regulator IC is based on the fact that current is proportional to voltage and can be controlled by the voltage applied to a resistor. When the input voltage is greater than the output voltage, the device sinks the excess current and acts as a load. This causes the output voltage to drop until the desired output voltage is attained. In this way, the device regulates the voltage applied to the load.The device has a short-circuit protection circuit which kicks in when the current exceeds 11A. It also has thermal protection circuits that turn off the output when the junction temperature exceeds a certain threshold. It also features a programmable module for setting the output voltage and an optional output capacitor for improved efficiency.Overall, the NCV78M12BDTRKG is a high performance and efficient linear voltage regulator IC suitable for a wide range of applications. It is easy to use and requires minimal external components for operation, making it a great choice for power management applications.
