 * @brief Charger 18 Click Example.
 *
 * # Description
 * This example demonstrates the use of Charger 18 click board by controlling
 * the status of the charger as well as the LDO and BUCK regulators.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the chip with the charger, LDO and BUCK regulators disabled.
 *
 * ## Application Task
 * This function enables the charger, BUCK and LDO in the span of 25 seconds, and displays
 * the status of each feature on the USB UART.
