FAN9673Q Description

Short technical summary and product information.

The FAN9673Q is an advanced three-channel interleaved Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC from ON Semiconductor. It is engineered for PFC pre-regulator applications, enabling the design of power supplies that comply with stringent standards like IEC1000-3-2.

 

Key features include average current-mode control, a PFC slave channel management function for improved load transient response, and a programmable operation frequency range of 18 kHz to 40 kHz or 55 kHz to 75 kHz. The device also supports a programmable PFC output voltage and incorporates essential protection functions such as peak current limiting, input voltage brownout protection, and TriFault Detect.

 

Designed for surface mount installation, the FAN9673Q is housed in a compact 32-pin LQFP package (7x7 mm). It operates across a wide temperature range of -40°C to 105°C, making it suitable for various demanding applications. The controller requires a supply voltage of 15V and has a startup current of 30 µA.

 

Typical applications for the FAN9673Q include high-power AC-DC power supplies, DC motor power supplies, white goods like air conditioners, server and telecom power supplies, and industrial welding equipment.
