LED Drivers

24-channel LED driver12-bit PWMconstant-current sinkVQFN-32internal oscillator

TLC5947RHBR is a 24-channel constant-current LED sink driver with 12-bit PWM dimming and an internal oscillator for LED display and illumination control.

Best for

  • Multi-channel static LED displays
  • PWM LED brightness control
  • Daisy-chained LED driver designs

Avoid if

  • Per-channel analog current programming is required
  • LED current above 30 mA per output is required
  • A pre-initialized output state at power-up is mandatory

Check before use

  • Program RIREF for the required sink current
  • Keep BLANK high during power-up until valid grayscale data are latched
  • Provide a soldered thermal pad and adequate copper area
  • Verify output voltage and package dissipation for the LED load
