使用 MPM3632C 和 PIC32MZ2048EFH100 产生低于输入电压的输出电压

/*!
 * @file main.c
 * @brief Buck 10 Click Example.
 *
 * # Description
 *  Demo application shows basic usage of Buck 10 Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 *  Configuring Clicks and log objects.
 *  Settings the Click in the default configuration.
 * 
 * ## Application Task  
 *  Enable and Disable device every 5 seconds.
 *
 * @note
 *  Input voltage recommended range - from 4V to 18V
 *  Low-side valley current limit - from 3A to 3.9A
 *  Low-side negative current limit - (-2.5A)
 *  Output voltage - 3.3V or 5V
