FAN4803CP1 General Description

The FAN4803CP1 is a current-mode control PFC controller designed for use in power factor correction applications. It operates at a fixed frequency of 75kHz and features a proprietary multiplier that simplifies the design of power factor correction circuits. This controller includes a high voltage start-up current source, programmable output over-voltage protection, and built-in leading-edge blanking for high-side gate drive signals. The FAN4803CP1 also has a low startup current of 200μA, making it suitable for low power consumption applications.The device is housed in a 16-pin PDIP package and operates over a wide temperature range of -40°C to 125°C. It requires an external MOSFET switch and current sense resistor to complete the power factor correction circuit. Additionally, this controller offers protection features such as input under-voltage lockout and over-temperature protection.
