TPS61194EVM LED Driver Evaluation Modules

Texas Instruments TPS61194EVM LED Driver Evaluation Modules (EVMs) help designers evaluate the operation and performance of the TPS61194. This evaluation module uses the TPS61194 to drive up to 4 LED strings (up to 12 LEDs each, 36 LEDs together) for LCD backlighting with high efficiency. The power supply connection for the battery and test points for each signal can be found on the evaluation board. An external PWM signal can control the LED brightness. A separate LED board can be used to load or connect the LCD panel to the output connector. The Texas Instruments TPS61194Q1-EVM is designed to test the AEC-Q100 qualified version for automotive applications.
