FAN5346

Series Boost LED Driver with PWM Dimming Interface

Description

Features

The FAN5346 is an asynchronous constant-current LED

Asynchronous Boost Converter

Drives LEDs in Series:

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.

5kHz to 100kHz PWM Dimming Frequency Range

1.2MHz Fixed Switching Frequency

Soft-Start Capability

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.

Input Under-Voltage Lockout (UVLO)

Output Over-Voltage Protection (OVP)

Short-Circuit Detection

The FAN5346 is available in a 6-lead SSOT23 package. It is

“green”

and

RoHS

compliant.
