3xBuck click is a triple step-down (buck) converter Click board™. It features three independent output terminals that can provide 1.8V, 3.3V, and 5V with the combined current output up to 3A. This specific selection of output voltages makes this Click board™ a perfect choice for an embedded application power supply, as these voltages are the most commonly used values. The voltage at each output can be switched to a programmable internal voltage divider, in cases when the output voltage fine-tuning is required. This can be done over the industry-standard I2C interface
