A6280 - 3-Channel Constant-Current LED Driver

Description

The A6280 is a 3-channel constant current LED driver that has a wide range of output currents.

The A6280 controls LED brightness with a Pulse Width Modulation (PWM) scheme that gives the application the capability of displaying a billion colors in an RGB cluster.

Features

  • 3 × 10-bit PWM brightness settings.
  • 3 × 7-bit dot correction current settings.
  • 5 to 17 V operation.
  • Wide output current range, 10 to 150 mA per channel.
  • Serial port/PWM clock operates at up to 5 MHz.
  • Data and clock logic architecture allows single microcontroller control of large quantities of seriallyconnected A6280s at fast data transfer rate.
  • Buffered logic outputs to drive cables.
  • Thermal shutdown and UVLO protection.
  • Power-On Reset Packages: 16-.
