FAN5340 Datasheet Synchronous Constant-current Series Boost Led Driver

Manufacturer: Fairchild (now onsemi)

Overview: FAN5340 — Synchronous Constant-Current Boost Series LED Driver with PWM Brightness Control L1 April 2010 FAN5340 Synchronous Constant-Current Series Boost LED Driver with PWM Brightness Control and Integrated Load.

General 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.

For safety, the device
