ARC3C0845 - High Efficiency LED Backlight Driver

General Description

The ARC3C0845/ARC3C0845W is an ultra-high efficiency DC/DC converter solution with integrated programmable current sinks that drive up to eight strings of LEDs.

The ARC3C0845/ARC3C0845W integrates all MOSFETs and their control & driver circuitry.

Key Features

  • Synchronous DC/DC converter with integrated FETs.
  • 2- and 3-cell Li-Ion battery input voltage: 4.5V to 15V.
  • Proprietary architecture for ultra-high LED efficiency, above 88% over the entire operating range.
  • Integrated output disconnect switch.
  • Up to 45V 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 3bit dithering.
  • Supports linear/logarithmic analog and PWM.

Description The ARC3C0845/ARC3C0845W is an ultra-high efficiency DC/DC converter solution with integrated programmable current sinks that drive up to eight strings of LEDs. The ARC3C0845/ARC3C0845W integrates all MOSFETs and their control & driver circuitry. With the proprietary architecture, the ARC3C0845/ARC3C0845W provides the highest efficiency (>94%) possible in a compact 3.44 mm x 2.415 mm WLCSP40 (ARC3C0845W) or 4 mm x 4 mm 32-pin LGA package (ARC3C0845). The high switching frequency enables a small and low profile solution size aligned to the needs of the latest mobile products.
