Analog Devices ADP8140 LED Drivers with adaptable power control offers high current control with up to four LED drivers. Each driver can sink up to 500mA. The sink current is programmed for all four drivers with one external resistor. ADP8140 features a feedback output that controls an external power supply for optimal efficiency. In addition, the ADP8140 protects the LEDs, power supply, and itself against thermal events, short circuits, overvoltages, and LED open circuits. Designers can easily connect multiple ADP8140 ICs in parallel to drive additional LED strings or higher current LEDs. Available in a small, thermally-enhanced, lead frame chip scale package (LFCSP), the ADP8140 is ideal for high brightness LED lighting and large format LED backlighting.
