This EVB shows the functionality of MC34844 setup with variable operation parameters. The MC34844 is a high efficiency, LED driver for use in backlighting LCD displays from 10” to 20”+ can operate in this demo board from a supply of 24V. The device is capable of driving up to 160 LEDs in 10 parallel strings. The current through these 10 channels is matched to within ±2% and can be programmed via the I2C/SM-bus interface or using direct PWM input.
For evaluation purposes this Demo Board includes a USB to I2C bridge that allows control the EVB via USB communication though a PC. All these control fuctions are gathered in a friendly GUI (Graphical Unit Interface) also provided along with the Demo Board.
This evaluation board allows the user to test this device on its three operational modes: Master Mode, Slave Mode and Stand Alone Mode by facilitating access to all pins and providing different possible component configuration.
