 * \brief Buck 3 Click example
 * 
 * # Description
 * This example demonstrates the use of Buck 3 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and configures the Click board.
 * 
 * ## Application Task  
 * Checks the PGD pin state which signalize the undervoltage or overvoltage fault or
 * the thermal shutdown condition. 
 * If there's any of the above faults detected it logs a desired message on USB UART.
