ADP8140 Used with Buck GENERAL DESCRIPTION The ADP8140 provides high current control of up to four LED circuits, overvoltages, and LED open circuits. Multiple drivers. Each driver can sink up to 500 mA. The sink current is ADP8140 ICs are easily connected in parallel to drive additional programmed for all four drivers with one external resistor. LED strings or higher current LEDs. The ADP8140 is available in a small, thermally enhanced, lead frame chip scale package The device features a feedback output that controls an external (LFCSP). power supply for optimal efficiency. The ADP8140 also protects the LEDs, power supply, and itself against thermal events, short Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
