Analog Devices Inc. ADP8140EB Evaluation Board
Analog Devices Inc. ADP8140EB Evaluation Board is designed to evaluate the ADP8140 4-channel, high-current, LED drivers with adaptable power control. The ADP8140EB board includes an ADP8140 with a P-channel Metal-Oxide Semiconductor (PMOS) field effect transistor regulation stage to power the LEDs. The PMOS is connected in series to the 24V supply, which helps drop the excess voltage.
Features
- Voltage ranges
- 8V to 30V for three LEDs
- 15V to 30V for six LEDs
- 125μA to 350mA current sink range (four adjustable channels)
- Analog and PWM dimming inputs and LED current outputs
- Feedback output controls external power source for optimal efficiency and safety
- DC power supply required (not included)
Applications
- High-brightness LED lighting
- Large format LED backlighting
