BUCK 7 click

Buck 7 Click is a high-efficiency buck (step-down) DC-DC converter, which can provide digitally adjusted step-down voltage on its output while delivering up to 3.5A of current.

Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : SPI type

Software Support

We provide a library for the BUCK7 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 BUCK7 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void buck7_cfg_setup ( buck7_cfg_t *cfg );

  • Initialization function.

    BUCK7_RETVAL buck7_init ( buck7_t *ctx, buck7_cfg_t *cfg );

  • Click Default Configuration function.

    void buck7_default_cfg ( buck7_t *ctx );

Example key functions :

  • Function for settings output voltage.

    void buck7_set_output_voltage ( buck7_t *ctx, uint16_t voltage );

  • Function for enable chip

    void buck7_enable ( buck7_t *ctx );

  • Function for settings chip mode

    void buck7_set_mode ( buck7_t *ctx, uint8_t mode );

Examples Description

This demo application controls the voltage at the output using the BUCK 7 click.

The demo application is composed of two sections :

Application Init

Initializes Driver init, reset chip, enable chip and set mode

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
buck7_cfg_setup( &cfg );
BUCK7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
buck7_init( &buck7, &cfg );
buck7_enable( &buck7 );
}

Application Task

Sets output voltage to 5V, 10V, 15V, 20V, 25V every 3 seconds. It is necessary to set the input voltage on 2.7V + maximum output voltage.

{
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
buck7_set_output_voltage( &buck7, 0x0BB8 ); /* 10 V */
Delay_ms( 3000 );
}

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.BUCK7

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.
