ADP8140 4 Channel High Current LED Driver with Adaptable Power Control
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 which 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, LFCSP (lead frame
chip scale package).
