FAN4803 Description

Short technical summary and product information.

The FAN4803 from ON Semiconductor is a compact controller designed for power factor corrected, switched mode power supplies. It provides very low start-up and operating currents, making it suitable for space-constrained applications.

 

This controller integrates circuits for both a leading edge, average current "boost" type PFC and a trailing edge PWM. Key electrical specifications include a minimum input voltage of 9.6V and a maximum of 15V, with an operating voltage typically around 17.5V. It has a maximum output current of 1A and a maximum supply current of 4mA.

 

The FAN4803 is housed in a DIP package and is designed for through-hole mounting. It operates within a temperature range of 0°C to 70°C.

 

This component is part of the PFC (Power Factor Correction) category, falling under the broader Power Management PMIC and Integrated Circuits (ICs) classifications.
