STEVAL-ILL015V2

HB LED driver with diagnostics based on the LED2472G and

STM32

Data brief

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

Description

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.
