LED Drivers

RGB LED driver9-channelI2C12-bit PWM29 kHz PWMconstant-current sinkWQFN-20

LP5009RUKR is a 9-channel I2C constant-current RGB LED driver for up to three RGB LED modules, with 12-bit PWM dimming at 29 kHz and a compact WQFN-20 package.

Best for

  • Compact RGB LED indicators
  • Three RGB LED modules with independent brightness control
  • Low-noise LED dimming above the audible range

Avoid if

  • More than nine independently controlled LED channels are required
  • The required LED current exceeds the device current limits
  • The design cannot provide adequate thermal copper area

Check before use

  • Set RIREF using the datasheet current-setting equation
  • Verify output voltage headroom for each LED
  • Connect VCAP to a 1 µF capacitor to GND
  • Use a valid non-floating I2C address configuration
