ST ILL003V2 User Manual
High brightness 32-LED evaluation board without diagnostic
based on the STP16CP05 LED driver
Features
■ 32 LED matrix driven by STP16CP05
■ LED current regulation
■ Adjustable brightness
■ Animated text capability
■ Adjustable blinking speed; several blinking
modes
■ Input voltage ranges from 5 V to 35 V input
voltage range
■ DC-DC converter for high efficiency
Description
This evaluation board represents a cost effective
solution to drive an array of high brightness LEDs,
using the LED driver STP16CP05. This driver
provides the same constant current for each of its
output channels, thus there is no difference in
brightness and color between the LEDs.
