Description

General part information

FAN7346 Series

The FAN7346 is an LED current-balance controller that controls 4-LED arrays to maintain equal LED current.The FAN7346 has a high withstanding voltage, so is suitable for edge-type LED BLU and LED Lighting. To minimize components between primary to secondary, the FAN7346 generates a new integrated feedback signal.The FAN7346 provides various protections, such as over-voltage regulation, open-LED protection, thermal protection, and drain-source voltage protection of regulating switch (the FAN7346 monitors all LED arrays drain-source voltage for protection). To increase system reliability, FAN7346 applies individual string protection. Because FAN7346 integrates so many functions it reduces overall BOM costs.LED brightness can be linearly varied up to LED current by applying an external Pulse Width Modulated (PWM) signal to the PWM pin.The FAN7346 is available in a 28-SOIC package.
