Boost 3 Click

Boost 3 Click is a compact add-on board that contains a boost converter with an integrated current mirror function. This board features the TPS61391, a 700-kHz pulse-width modulating (PWM) Step-Up converter with a 70V switch FET with an input voltage up to 5.5V from Texas Instruments.

Click library

• Author : MikroE Team
• Date : Sep 2020.
• Type : GPIO type

Software Support

We provide a library for the Boost3 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 Boost3 Click driver.

Standard key functions :

• Config Object Initialization function.

  void boost3_cfg_setup ( boost3_cfg_t *cfg );

• Initialization function.

  BOOST3_RETVAL boost3_init ( boost3_t ctx, boost3_cfg_t cfg );

Example key functions :

• Function is used to enable or disable the device.

  void boost3_dev_enable ( boost3_t *ctx, uint8_t state );

Examples Description

Boost 3 Click provides an adjustable output voltage through the onboard potentiometer. The chip is a 700-kHz pulse-width modulating (PWM) step-up converter with an 85-V switch FET with an input ranging from 2.5 V to 5.5 V.

The demo application is composed of two sections :

Application Init

Initializes GPIO and LOG structures, and set CS pin as output.

void application_init ( void )
{
    log_cfg_t log_cfg;
    boost3_cfg_t cfg;

    /** 
     * 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.

    boost3_cfg_setup( &cfg );
    BOOST3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    boost3_init( &boost3, &cfg );
}

Application Task

Turns ON the device for 10 seconds and then turns it OFF for 3 seconds. It also displays appropriate messages on the USB UART.

void application_task ( void )
{
    boost3_dev_enable( &boost3, BOOST3_ENABLE );

    log_printf( &logger, "The Click board is enabled!\r\n" );
    log_printf( &logger, "Please use the on-board potentiometer" );
    log_printf( &logger, " to adjust the voltage output.\r\n" );
    log_printf( &logger, "--------------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    boost3_dev_enable( &boost3, BOOST3_DISABLE );
    log_printf( &logger, "The Click board is turned OFF!\r\n" );
    log_printf( &logger, "--------------------------------\r\n" );
    Delay_ms ( 1000 );
    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.Boost3

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.
