Overview

The Texas Instruments LP8556TM-EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LP8556 High-Efficiency LED Backlight Driver. The device features high efficiency boost DC-DC converted and 6 high-precision current sinks that can be controlled by either a PWM signal or an I2C master. In addition to the main board featuring the LP8556TME-E05, the module features a USB-I2C Interface Board and an LED Board. The USB-I2C Interface Board coupled with the evaluation software enables easy device control and configuration of all device features. The LED board provides a configurable array of 72 side emitting white LEDs.
