The TPS61194EVM evaluation module (EVM) helps designers evaluate the operation and performance of this device.  The  TPS61194EVM uses the TPS61194 to drive up to 4 LED strings (up to 12 LEDs each, 36 LEDs together) for LCD backlighting with high efficiency.  Information about output voltage and current ratings of TPS61194EVM can also be found in the TPS61194 datasheet.  Power supply connection for the battery and test points for each signal can be found on the evaluation board.  LED brightness can be controlled by external PWM signal.  Separate LED board can be used as a load or it is possible to connect LCD panel to the output connector.
