FAN5340

Synchronous Constant-Current Series Boost LED Driver

with PWM Brightness Control and Integrated Load

Disconnect

Features

Description

The FAN5340 is a synchronous constant-current LED driver

capable of efficiently delivering up to 500mW to a string of up

to four LEDs in series. Optimized for small form-factor

applications, the 1.2MHz fixed switching frequency allows

the use of chip inductors and capacitors.

Synchronous Current-Mode Boost Converter

Up to 500mW Output Power

Supports 2, 3, or 4 LEDs in Series

2.7V to 4.8V Input Voltage Range

1.2MHz Fixed Switching Frequency

1mA Maximum Quiescent Current

Soft-Start Capability

For safety, the device features integrated short-circuit

detection plus over-voltage and thermal shutdown

protections. In addition, input under-voltage lockout

protection is triggered if the battery voltage is low.

Brightness (dimming) control is implemented by applying a

PWM signal of 300Hz to 1kHz on the EN pin. During

shutdown, the FAN5340 disconnects the LED anodes from

the output of the boost regulator, which holds the boost

regulator’s voltage on C_OUT, reducing audible noise from the

PWM dimming and removing power from the LED string.
