LP8861Q1EVM

TEXAS INSTRUMENTS  LP8861Q1EVM  评估电路板, LP8861-Q1, 发光二极管驱动器 新

The evaluation module EVM helps designers evaluate the operation and performance of this device.  The LP8861Q1EVM uses the LP8861-Q1 to drive up to 4 LED strings up to 12 LEDs each, 48 LEDs together for LCD backlighting with high efficiency.  Information about output voltage and current ratings of LP8861Q1EVM can also be found in the LP8861-Q1 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.  Temperature based LED current reduction can be evaluated with external or mounted of EVM NTC sensor.
