KIT34845EPEVME Datasheet PDF - NXP

●This Evaluation board shows the functionality of MC34845 set up under specific operation parameters. MC34845 which is a high efficiency, LED driver for use in backlighting LCD displays from 10" to 17"+ can operate in this demo board from a supply of 5V, the device is capable of driving up to 96 LEDs in 6 parallel strings. The current through these 6 channels is matched to within ±2%. For evaluation purposes this Demo Board includes a simple MCU that allows control of the light dimming of the LEDs as well as the PWM frequency from 200Hz to 26.5kHz.

● Four Layer Board

● Low Noise Design
