Description
The LP8556 device is a white-LED driver featuring an asynchronous boost converter and six high precision current sinks that can be controlled by a PWM signal or an I2C master.
Features
- 1 High-efficiency DC/DC boost converter with integrated 0.19-Ω power MOSFET and three switching frequency options: 312 kHz, 625 kHz, and 1250 kHz.
- 2.7-V to 36-V Boost switch input voltage range supports multi-cell Li-Ion batteries (2.7-V to 20-V VDD input range).
- 7-V to 43-V Boost switch output voltage range supports as few as 3 WLEDs in series per channel and as many as 12.
- Configurable channel count (1 to 6).
- Up to 50 mA per channel.
- PWM an.
