LT8391D Evaluation Board (EVAL-LT8391D-AZ)

Analog Devices Inc. LT8391D Evaluation Board (EVAL-LT8391D-AZ) is a reference design for a buck-boost LED driver circuit based on the LT8391D LED Controller. The LT8391D is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation or internal ±15% triangle spread spectrum operation for low EMI. With 4V to 60V input, 0V to 60V output, and seamless low noise transitions between operation regions, the LT8391 is ideal for LED driver and battery charger applications in automotive, industrial, and battery-powered systems.
