HB LED without diagnostic (32 LED) based on STP16CP596
Features
■ 32 LEDs matrix is driven by STP16CP596
■ LED current regulation
■ Adjustable brightness
■ Animated text implemented
■ Adjustable blinking speed, several blinking
modes
■ Input voltage ranges from 5 V to 35 V
■ DC/DC converter for high efficiency
Description
This evaluation board implements a cost effective
solution to drive an array of high brightness LEDs,
using the LED driver STP16CP596. 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.
