发现使用MAX17506和STM32F446RE的降压转换魔力

 * \brief Buck5 Click example
 * 
 * # Description
 * Buck 5 Click is a high-efficiency buck DC/DC converter, which can provide digitally 
 * adjusted step-down voltage on its output while delivering a considerable amount of current. 
 * Buck 5 Click accepts a wide voltage range on its input - from 5V to 30V. The output voltage 
 * may be adjusted via the SPI interface, in the range from 0.9V to approximately 5.5V.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver init, and enables the Click board.
 * 
 * ## Application Task  
 * Increases the output voltage by 500mV every 3 seconds from MIN to MAX VOUT.
