Description

This is a Boost LED driver designed drive white LED with constant current. It can drive 2 ~ 6 LED in a series connection from a single Li-Ion cell ensuring uniform brightness in small screen backlighting applications. The device also supports a single feedback of parallel connected multiple strings of LEDs for driving higher number of LEDs. It is available in SOT26, low profile TSOT26 and the extremely thin and small footprint U-DFN2020-6 Type C.

Application(s)

  • Portable Navigation Device/GPS receiver,
  • PMP4 player,
  • Portable Media Players,
  • Digital Photo Frames,
  • Digital Radio Displays,
  • Mobile phones/PDA
