PE23108 - High-Efficiency LED Backlight Driver

General Description

The PE23108 is an ultra-high efficiency DC-DC converter solution with integrated programmable current sinks that drive up to eight strings of LEDs.

The PE23108 integrates all MOSFETs and their control and driver circuitry.

Key Features

  • Synchronous DC-DC converter with integrated FETs.
  • 2- and 3-cell Li-ion battery input voltage for LED boost: 4.5V to 15V.
  • 2.7V to 5.5V IC input voltage.
  • Proprietary architecture for ultra-high LED efficiency, up to 96%.
  • Integrated output disconnect switch.
  • Up to 42V output for maximum flexibility in assignment of LEDs to strings and selection of LED forward voltage.
  • Up to 12-bit dimming resolution with an additional 3-bit dithering.
  • Linear/logarithmic anal.
