Smart Buck 3 click

Smart Buck 3 Click is a compact add-on board that contains a high-frequency synchronous step-down DC-DC converter. This board features the TPS62366A, a processor supply with I2C compatible interface and a remote sense from Texas Instruments. As input, it uses voltages in the range of 2.5V up to 5.5V, including support for common battery technologies. As output, the converter can scale voltage from 0.5V up to 1.77V in 10mV steps, retaining up to 2.5A peak output current, operating at 2.5MHz of the typical switching frequency.

Software Support

We provide a library for the Smart Buck 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 Smart Buck 3 Click driver.

Example Description

This example demonstrates the use of Smart Buck 3 Click boardâ„¢. This driver provides functions for device configurations and for the sets and reads the output voltage.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After initializing the driver, the default configuration is executed and the device is turned on.

void application_init ( void )
{
log_cfg_t log_cfg;
smartbuck3_cfg_t smartbuck3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
smartbuck3_cfg_setup( &smartbuck3_cfg );
SMARTBUCK3_MAP_MIKROBUS( smartbuck3_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == smartbuck3_init( &smartbuck3, &smartbuck3_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
Delay_ms( 100 );
if ( SMARTBUCK3_ERROR == smartbuck3_default_cfg ( &smartbuck3 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
Delay_ms( 100 );
log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Smart Buck 3 Click boardâ„¢. Changes the output voltage every 3 seconds and displays the current voltage output value. Results are sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
if ( SMARTBUCK3_OK == smartbuck3_set_voltage( &smartbuck3, vout_mv ) )
{
Delay_ms( 100 );
if ( SMARTBUCK3_OK == smartbuck3_get_voltage( &smartbuck3, &vout_mv ) )
{
log_printf ( &logger, " Vout: %u mV\r\n", vout_mv );
}
}
vout_mv += 100;
if ( vout_mv > SMARTBUCK3_VOUT_MAX )
{
}
Delay_ms( 3000 );
}

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.SmartBuck3

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.
