The FAN5346 is an asynchronous constant-current LED driver that drives LEDs in series to ensure equal brightness for all the LEDs. FAN5346S20X has an output voltage of 20V and can drive up to 5 LEDs in series. FAN5346S30X has an output voltage of 30V and up to 8 LEDs in series. Optimized for small form-factor applications, the 1.2MHz fixed switching frequency allows the use of small inductors and capacitors. The FAN5346 uses a PWM dimming control interface to set the brightness levels of the LEDs. A PWM signal of 5kHz to 100kHz is applied to the EN pin. For safety, the device features integrated over-voltage, over-current, short-circuit detection, and thermal-shutdown protections. In addition, input under-voltage lockout protection is triggered if the battery voltage is too low. The FAN5346 is available in a 6-lead SSOT23 package. It is “green” and RoHS compliant.
