FAN5341 - ON Semiconductor

FAN5341 Series Boost LED Driver

The FAN5341 is an asynchronous constant−current LED driver capable of efficiently delivering up to 500 mW to a string of up to five LEDs in series. Optimized for small form−factor applications, the 1.2 MHz fixed switching frequency allows the use of small chip inductors and capacitors. The FAN5341 uses a simple single−wire digital control interface to progra.

Features

integrated over−voltage, over−current, short−circuit detection, and thermal−shutdown protection. In addition, input under−voltage lockout protection is triggered if the battery voltage is too low. The FAN5341 is available in a very low profile, small form−factor 2 mm x 2 mm x 0.55 mm 6−lead UMLP package that is green and RoHS compliant. Features
