Buck 13 click

Buck 13 Click is a high-efficiency step-down converter which provides a highly regulated output voltage derived from the connected power source, rated from 4.5V to 5.5V.

Click library

• Author : Petar Suknjaja
• Date : Dec 2019.
• Type : SPI type

Software Support

We provide a library for the Buck13 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

‍This library contains API for Buck13 Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void buck13_cfg_setup ( buck13_cfg_t *cfg );

  - Initialization function.

  ‍BUCK13_RETVAL buck13_init ( buck13_t *ctx, buck13_cfg_t *cfg );

• Click Default Configuration function.

  ‍void buck13_default_cfg ( buck13_t *ctx );

Example key functions :

• Enables the Buck 13 output.

  ‍void buck13_enable ( buck13_t *ctx, uint8_t pwr_state );

  - Gets the ADC values from the module.

  ‍uint16_t buck13_get_adc( buck13_t *ctx );

• Gets the output voltage.

  ‍uint16_t buck13_get_voltage( buck13_t *ctx );

  Examples Description

‍This example switches the output of the Buck13 and logs the output voltage on the Vout terminal.

The demo application is composed of two sections :

Application Init

>Initializes driver and turns OFF the Buck 13 output as default state.

void application_init ( void )
{
    log_cfg_t log_cfg;
    buck13_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    buck13_cfg_setup( &cfg );
    BUCK13_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    buck13_default_cfg ( &buck13 );
    buck13_init( &buck13, &cfg );
    log_info( &logger, "Buck 13 is enabled now" );
}

Application Task

‍Displays the output voltage every 2 seconds.

void application_task ( void )
{
    //  Task implementation.
 
    buck13_enable( &buck13, BUCK13_ENABLE ); 
    out_voltage = buck13_get_voltage( &buck13 );
    log_printf( &logger, "Vout =  %d mV\r\n", out_voltage );
    
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Buck13

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
