Description

The LP8545 is a white LED driver with integrated boost converter. It has six adjustable current sinks which can be controlled by PWM input or with I2C-compatible serial interface.

Key Features

  • High-voltage DC/DC boost converter with integrated FET
  • 8 to 13 true bit (steady state)
  • Additional 1 to 3 bits using dithering during brightness changes I2C and PWM brightness control PWM output frequency and LED current set
