FAN5341UMPX Description

Short technical summary and product information.

The FAN5341UMPX from ON Semiconductor is an asynchronous constant-current LED driver designed for small form-factor applications. It efficiently delivers up to 500 mW to a series string of 3 to 5 LEDs. The device operates with a wide input voltage range of 2.7 V to 5.5 V and features a fixed 1.2 MHz switching frequency, enabling the use of small external components.

 

This LED driver utilizes a simple single-wire digital control interface to program LED brightness levels in 32 linear steps. For enhanced safety and reliability, the FAN5341UMPX includes integrated over-voltage, over-current, short-circuit detection, and thermal shutdown protection. Input under-voltage lockout is also provided.

 

The FAN5341UMPX is housed in a low-profile, 2 mm x 2 mm x 0.55 mm 6-lead UMLP package. It is Pb-Free, Halogen Free/BFR Free, and RoHS compliant, making it suitable for various portable electronic devices.

 

Applications include cellular mobile handsets, mobile internet devices, portable media players, PDAs, DSCs, and MP3 players.
