NCP1071STAT3G is a high-performance, low-Cost, monolithic switching voltage regulator featuring an integrated 400mΩ power switch. This power regulator is capable of delivering up to 1.5A of continuous output current and has a wide input voltage range of 4.5V to 30V. The NCP1071STAT3G is especially well-suited for low-noise, high performance, offline applications such as LED lighting, DC brushed motor controllers, AC/DC converters, and power supplies.

The NCP1071STAT3G is a high-efficiency power regulator which includes a reference voltage, an error amplifier, temperature protection and current sensing circuitry, and high side and low side switches. The device can be configured for constant voltage or constant current regulation based on the application. The device also has an adjustable switching frequency (up to 2MHz), over-temperature protection, and an adjustable current limit.

The NCP1071STAT3G is designed to provide high-efficiency power conditioning for a wide variety of applications from LED lighting to off-line AC/DC converters and power supplies. Specifically, the device is well-suited for automotive, industrial, medical, and consumer applications. The device can be used as an AC/DC buck or boost converter, or as a SEPIC converter, depending on the input and output voltages. The device has a wide input voltage range of 4.5V to 30V, an adjustable soft-start, adjustable switching frequency, and over-temperature protection.

The operation of the NCP1071STAT3G begins when an input voltage is applied to the regulator. The reference voltage circuit sets the output voltage of the regulator, while the error amplifier monitors the output voltage and ensures that the voltage remains constant. When an output load is applied, the regulator reduces the switching frequency to maintain the set output voltage. If the output current reaches the adjustable current limit, the regulator will shut down and enter a latch mode to protect the output from overloading or short-circuiting. Finally, the device has an over-temperature protection circuit which will shut down the regulator when the temperature exceeds a specified limit.

The NCP1071STAT3G is a high-performance, low-cost, low-noise, high-efficiency power regulator ideal for a wide range of offline, low-power applications from LED lighting to AC/DC converters and power supplies. The device has a wide input voltage range, adjustable switching frequency, adjustable soft-start, adjustable current limit, and over-temperature protection. The device is well-suited for automotive, industrial, medical, and consumer applications and provides a high-efficiency power conditioning solution.
