NCV662SQ25T1G is a 3-in-1 voltage regulator, equipped with an adjustable output limit, also known as an adjustable short-circuit protection and thermal protection. It integrates an adjustable voltage-mode control with an adjustable current-mode control. DC/DC converters integrated with an N-Channel FET and a voltage detector, improves efficiencies and power savings by reducing unwanted power consumption. Its wide input range from 6V~36V makes it suitable for different voltage sources. With an output voltage range of 1.1V~ 5.5V, the current limit is adjustable from 0.56A to 5.5A. The application of NCV662SQ25T1G includes Automotive, industrial, telecom, and many other applications.

The components and devices that make up the NCV662SQ25T1G are the output voltage detector, current sense amplifier, a digital-to-analog converter, an operational amplifier, and an optional switch-mode power supply controller. The output regulator module is composed of the operational amplifier and the output current limit components, which control the output power level and distribution of the output current. The current sense amplifier detects the load current, and the digital-to-analog converter adjusts the output voltage as needed. Additionally, the power supply controller manages the output characteristics and also controls shutdown and short circuit protection. The output current limit can be adjusted, which helps to ensure safe operation.

The working principle of NCV662SQ25T1G consists of two functions: current and voltage limitation. The current limit is achieved by comparing the voltage across the sense resistor and the reference voltage, which is set by the regulator. The voltage limitation is achieved by comparing the input voltage and the reference voltage. The input voltage is adjusted by the digital-to-analog converter and changes the reference voltage. If the fet closes, the output voltage is limited by the voltage divider, ensuring safe operation. The safety features enable the NCV662SQ25T1G to protect itself from overload.

The NCV662SQ25T1G is an efficient voltage regulator with the ability to adjust its output power limit, providing power stability and reliability to a variety of applications. As a reliable and cost-effective solution, the NCV662SQ25T1G is applied in various power-regulated circuits such as automotive systems, industrial equipment, telecommunications and computers. Utilizing advanced thermal and short-circuit protection to ensure power savings, the NCV662SQ25T1G is the perfect choice for applications that require reliable and adjustable voltage regulation.
