Boost-INV 3 Click

Boost-INV 3 Click is a compact add-on board designed to supply positive/negative-driven applications. This board features the TPS65132, a dual-output power supply from Texas Instruments. The TPS65132 uses a single inductor scheme for both outputs to provide the user with the smallest solution size and high efficiency.

Software Support

We provide a library for the Boost-INV 3 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 Boost-INV 3 Click driver.

Example Description

This library contains API for the Boost-INV 3 Click driver.

This driver provides the functions to set the output voltage treshold.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART.

After driver initialization, default settings enable the positive and negative output and sets the output voltage to 4 V.

void application_init ( void )
{
log_cfg_t log_cfg;
boostinv3_cfg_t boostinv3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
boostinv3_cfg_setup( &boostinv3_cfg );
BOOSTINV3_MAP_MIKROBUS( boostinv3_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == boostinv3_init( &boostinv3, &boostinv3_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
Delay_ms ( 100 );
if ( BOOSTINV3_ERROR == boostinv3_default_cfg ( &boostinv3 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Boost-INV 3 Click board by changing

  • output voltage every 5 seconds starting from 4 V up to 6 V.
void application_task ( void )
{
for ( uint8_t n_cnt = BOOSTINV3_OUT_VOLTAGE_4V; n_cnt <= BOOSTINV3_OUT_VOLTAGE_6V; n_cnt++ )
{
err_t error_flag = boostinv3_set_pos_out( &boostinv3, n_cnt );
error_flag |= boostinv3_set_neg_out( &boostinv3, n_cnt );
if ( BOOSTINV3_OK == error_flag )
{
log_printf( &logger, " Set positive and negative voltage to %.1f V \r\n",
}
else
{
log_printf( &logger, " Error has occurred!!! \r\n" );
}
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
}

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.BoostINV3

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.
