The STEVAL-ILL015V2 product evaluation board provides a platform to test and evaluate the power logic LED driver LED2472G from STMicroelectronics.

The LED2472G is a 24-bit constant-current LED sink driver with output error detection, suitable for applications such as large-area displays and full-color board panels where improvement in RGB LED resolution and reduction of system cost are important.

Key features
  • Two LED2472G devices (TQFP48 package) connected to 3 x 16 RGB high-brightness LEDs
  • STM32 microcontroller
  • Cost-effective internal high-side oscillator
  • JTAG interface for microcontroller firmware changes/updates
  • Mini USB connector for interconnection with a PC GUI
  • Test points on the board for each important signal aid laboratory evaluation
  • Buttons and knob to control the board
  • Error and overtemperature flag for each LED driver
  • 3 jumpers to simulate the disconnection of 3 LEDs
  • 3 jumpers to simulate the shorting of 3 LEDs
  • Highly efficient ST1S010 DC-DC switching power supply
  • Input: 7.5 V to 18 V, 0.7 A
  • RoHS compliant
