STEVAL-ILL028V1
RGB LED driver for color displays and backlighting
based on the STP1612PW05 and STM32
Data brief
Features
■ Three STP1612PW05 (in QFN24 4 x 4 mm
packages) connected to 16 RBG high-
brightness LEDs
■ One STM32 microcontroller using an internal
HS oscillator
■ One ST1S10 high-efficiency switching DC-DC
power supply
■ 7.5 - 18 V DC power supply with
undifferentiated polarity and overvoltage
protection
■ DC input current: 0.7 A max, standard supply
connector
STEVAL-ILL028V1
■ LED current regulation
controlled through an STM32 microcontroller SPI
interface and DMA (optional).
■ Test points for each main signal
■ Microcontroller firmware update through JTAG
interface
■ Error LED and overtemperature LED for each
driver
■ 3 jumpers to disconnect the LEDs from the
driver to test error detection mode
■ 3 jumpers to enable LED shorting from the
driver to test error detection mode
■ Mini USB for board-to-PC connection
■ Incudes firmware to evaluate board features in
standalone and non-standalone modes:
– Adjustable color and brightness of each
LED
– Animated text
– GUI software for LED diagnostics
■ RoHS compliant
Description
The STEVAL-ILL028V1 demonstration board is
an RGB LED driver for color displays and
backlighting, designed as a platform for
demonstrating the performance of the
STP1612PW05 independent PWM LED driver,
