 * \brief Buck Boost 2 Click example
 * 
 * # Description
 * This application enables use of DC-DC step-down/step-up regulator (buck/boost).
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes Driver init and turn ON chip and settings mode with improvement current.
 * 
 * ## Application Task  
 * The Click has a constant output voltage of 5V, no additional settings are required.
