 * 
 * # Description
 * This aplication control voltage using Buck 11.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes I2C serial interface and selects the desired VDD voltage value
 * and VOUT value resolution (to get VOUT value in Volts).
 * 
 * ## Application Task  
 * Reads the averaged VOUT voltage calculated to Volts by performing a 30 conversions
 * in one measurement cycle. The measured results will be showed on the uart terminal every 300 milliseconds.
 * 
 * *note:* 
 * The user should measure the VDD voltage value and enter this measured value to the function as VDD value to get
 * more accurate measurement. This VDD voltage is used as reference voltage for the AD conversion.
 * 
 * The input voltage (VIN) range is from 4.2V to 60V.
 * The output current (IOUT) value should not be greater than 1.5A.
