Today, the NCP1602ACCSNT1G, a innovative power factor correction (PFC) controller from ON Semiconductor, is widely used for AC-DC power factor correction applications in both home and commercial products. This controller is designed to provide reliable and cost-effective power factor correction in fixed frequency AC input stages of AC-DC power supplies in applications such as lighting, industrial, portable electronics and office automation.

The NCP1602ACCSNT1G is an integrated PFC boost converter. It has a complete feature set, including a wide range of voltage and current regulation, built-in overvoltage protection, undervoltage lockout, and soft-start features. All of its features are highly configurable and can be customized to meet specific requirements. Additionally, this controller can be implemented with a low external component count, reducing costs and ensuring a higher quality solution.

The working principle of the NCP1602ACCSNT1G is based on the concept of boost conversion, which utilizes a high voltage transformer to step up the voltage to a level higher than the input power level. The power provided by the transformer is then regulated through a control loop to obtain a constant output voltage. This loop is adjustable to respond to changes in input voltage or load. The current regulation loop continuously monitors the inductor current for any deviations from the desired level and either increases or decreases the drive to the MOSFET to correct it.

The NCP1602ACCSNT1G also consists of a pre-regulator, power sequencer, and current share. The pre-regulator monitors the input voltage and automatically adjusts the other circuits to maintain a constant output voltage. The power sequencer distributes power to the various components of the device and also controls the switching of the primary switch MOSFET. Lastly, the current share feature allows multiple NCP1602ACCSNT1G devices to work together to provide a higher level of power.

The NCP1602ACCSNT1G is an excellent choice for a number of AC-DC power factor correction applications. This controller is capable of making small incremental adjustments to the output voltage in response to changes in the input voltage or load current, ensuring a smooth and stable output voltage. Additionally, its low external component count and flexibility for implementation make it a cost-effective solution for a wide variety of applications.
