Buck 10 Click

Buck 10 Click is a high-efficiency step-down converter which provides a highly regulated output voltage derived from the connected power source, rated from 4V to 18V. The regulated output voltage can be selected between two values: 3.3V and 5V. These are voltage values ​​that are most commonly used in many embedded designs. This Click is based around an integrated DC-DC converter, labeled as MPM3632C.

• Date : Jun 2021.
• Type : GPIO type

Software Support

We provide a library for the Buck10 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Buck10 Click driver.

Standard key functions :

• buck10_cfg_setup Config Object Initialization function.

  void buck10_cfg_setup ( buck10_cfg_t *cfg );

• buck10_init Initialization function.

  err_t buck10_init ( buck10_t *ctx, buck10_cfg_t *cfg );

Example key functions :

• buck10_set_device_mode This function enables and disables output of this Click board.

  void buck10_set_device_mode ( buck10_t *ctx, uint8_t mode);

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.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    buck10_cfg_t buck10_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.

    buck10_cfg_setup( &buck10_cfg );
    BUCK10_MAP_MIKROBUS( buck10_cfg, MIKROBUS_1 );
    if ( buck10_init( &buck10, &buck10_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Enable and Disable device every 5 seconds.

void application_task ( void ) 
{
    buck10_set_device_mode ( &buck10, BUCK10_DEVICE_ENABLE );
    log_printf(&logger, "Output:\t ENABLED\r\n");
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck10_set_device_mode ( &buck10, BUCK10_DEVICE_DISABLE );
    log_printf(&logger, "Output:\t DISABLED\r\n");
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Buck10

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
