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 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.
- Proprietary architecture for ultra-high LED efficiency, above 88% over the 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 3-bit dithering.
- Linear/logarithmic analog and PWM.
