ARC2C0608 Description
The ARC2C0608 is an ultra-high efficiency DC/DC converter solution with integrated programmable current sinks that drive up to six LED strings. The ARC2C0608 integrates all MOSFETs and their control and driver circuitry. With its proprietary architecture, the ARC2C0608 provides the highest efficiency (>94%) possible in a 35-lead pact wafer-level chip scale package (WLCSP).
ARC2C0608 Key Features
- Synchronous DC/DC converter with integrated FETs
- 2-cell Li-Ion battery input voltage: 4.5V to 13.2V
- Patented architecture for ultra-high LED efficiency, above 90% over entire operating range
- Integrated output disconnect switch
- Up to 30V output for maximum flexibility in assignment of LEDs to strings and selection of LED forward voltage
- 12 bits hybrid (mixed) linear dimming mode and 10 bits logarithmic mapping
- Up to 12 bits resolution with DC or PWM dimming
- Supports direct PWM dimming for maximum flexibility and resolution
- LED brightness ramp-up/ramp-down control with programmable ramp rate and linear/logarithmic ramp profiles
- Phase-shifted PWM dimming among active strings to minimize audible noise
