FAN4803CP2 Application Field and Working Principle

Power Factor Correction (PFC) is a technology used to improve the power efficiency of electrical equipment. The FAN4803CP2 is a Single-Stage Power Factor Correction (PFC) regulator designed to improve the power factor, reduce distortion and improve the power efficiency of a power network.The FAN4803CP2 is an innovative single stage power factor correction system with integrated active power factor correction (APFC) and low power quiescent current standby. This regulator is ideal for applications that require low cost solutions like LED lighting, air conditioner, industrial control systems and many others.The main purpose of FAN4803CP2 is to reduce current ripple effect, reduce disturbance, and improve the power efficiency of a power network. This is achieved by controlling the current input, which depends on the load demand, to the power network and maintaining the power factor near unity.The FAN4803CP2 is a single IC solution for power factor correction, making it easy to implement. It uses boost topology, with synchronous rectifiers to control the current input from the AC source and rectifies it for the load. This architecture has an efficiency greater than 90%.The FAN4803CP2 includes overcurrent, overvoltage, undervoltage, and open loop protection, as well as an output transient response time of less than 1µs.This PFC regulator also has selectable operating temperature, over current protection and current sense resistor to protect against current overload.The FAN4803CP2 control scheme consists of a PFC controller and two error amplifiers. The PFC controller consists of a voltage feedback error amplifier and a Current Error Amplifier (CEA). The CEA compares the input current with a reference and generates an error signal sent to the feedback loop to adjust the current input and maintain a power factor near unity.The FAN4803CP2 is designed to achieve high power factor and efficiency while minimizing power losses and system\'s conduction losses. It can be used in applications such as LED lighting, air conditioners, industrial control systems, server power supplies, and power amplifiers.The FAN4803CP2 is a cost-effective solution for power factor correction that enables high efficiency, low noise and low power loss. Its flexible design makes it suitable for applications ranging from residential and industrial to commercial, as well as in aviation and other transportation fields. Its integrated diagnostics and extensive protections give it long-term reliability, making it the perfect choice for any application that needs single-stage power factor correction.
