 * \brief 3xBuck Click example
 * 
 * # Description
 * This example demonstrates the use of the 3 x Buck Click Board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and performs the Click default configuration.
 * 
 * ## Application Task  
 * Alternates between predefined and default values for the Bucks output and 
 * logs the current set values on the USB UART.
 * 
 * @note
 * The default output voltage on Buck 1 is 1800mV, Buck 2 is 3300mV, and Buck 3 is 5000mV.
 * Configurable output voltage on all Bucks ranges from 680mV to 1950mV.
