16-channelconstant-current sink12-bit PWM6-bit dot correctionEEPROMHTSSOP-28

TLC5940QPWPREP is a 16-channel constant-current LED sink driver for independently PWM-controlled LED channels, with EEPROM-backed dot correction.

Best for

  • 16-channel LED brightness control
  • Applications requiring per-channel current trimming
  • Serially cascaded LED driver chains

Avoid if

  • The design requires a source driver rather than a current-sink driver
  • The required channel current exceeds the applicable operating-condition limit
  • The design cannot provide GSCLK and serial control signals

Check before use

  • Confirm LED forward voltage plus driver headroom remains within the 17 V output rating.
  • Calculate package dissipation for simultaneous active outputs and PWM duty cycle.
  • Initialize dot-correction and grayscale registers after power-up.
