使用MPM54304和STM32G431RB确保稳定和调节的输出电压

 * @brief Step Down 6 Click example
 *
 * # Description
 * This library contains API for the Step Down 6 Click driver.
 * This driver provides the functions to set the output voltage threshold.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, default settings sets output voltage to 550 mV.
 *
 * ## Application Task
 * This example demonstrates the use of the Step Down 6 Click board™ by changing 
 * output voltage every 5 seconds starting from 550 mV up to 1820 mV.
