- Small, thermally enhanced, LFCSP package (4 mm × 4 mm)
The ADP8140 provides high current control of up to four LED drivers. Each driver can sink up to 500 mA. The sink current is programmed for all four drivers with one external resistor.
The device features a feedback output that controls an external power supply for optimal efficiency. The ADP8140 also protects the LEDs, power supply, and itself against thermal events, short circuits, overvoltages, and LED open circuits. Multiple ADP8140 ICs are easily connected in parallel to drive additional LED strings or higher current LEDs. The ADP8140 is available in a small, thermally enhanced, lead frame chip scale package (LFCSP).
Applications
- High brightness LED lighting
- Large format LED backlighting
