ADP8140:  4 Channel High Current LED Driver with Adaptable Power Control

Product Details

Product Status:Pre-Release

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).

APPLICATIONS

  • High brightness LED lighting
  • Large format LED backlighting

FEATURES and BENEFITS

  • Highly integrated feature set gives a high brightness LED driver solution with minimal external components
  • Four current sink channels with adjustable currents from 0 to 500 mA
  • DC LED dimming for noiseless operation
  • 2% (max) matching between LED channels
  • 5% (max) LED current accuracy
  • Operates from Vin of 3.3 V to
    30 V. Higher voltages easily accomplished with small external circuit
  • Operates with LED anode supply voltages up to 100 Vdc
  • Feedback output controls external power source for optimal efficiency and safety
  • Multiple ADP8140 ICs can be operated in parallel and control one power supply
  • See data sheet for additional features
