使用TPSM63610和STM32F103RB产生低于输入电压的输出电压

/*!
 * @file main.c
 * @brief Step Down 10 Click example
 *
 * # Description
 * This library contains API for the Step Down 10 Click driver.
 * This driver provides the functions to set the output voltage treshold.
 *
 * 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 2 V.
 *
 * ## Application Task
 * This example demonstrates the use of the Step Down 10 Click board™ by changing 
 * output voltage every 2 seconds starting from 2 V up to 20 V.
