Buck 16 Click Board
Buck 16 Click Board
The Buck 16 Click Board™ is a compact add-on board that contains a DC-DC power converter that steps down the voltage from its input to its output. This board features the TPS62912, a high-efficiency, low noise, and low ripple current-mode synchronous buck converter from Texas Instruments. The TPS62912 has an output-voltage error of less than 1%, which helps ensure tight output-voltage accuracy, operates at a fixed switching frequency of 2.2MHz or 1MHz, and allows synchronization to an external clock.
The Buck 16 Click Board™ is suitable for noise-sensitive applications that generally use an LDO for post-regulation, such as high-speed ADCs, clock and jitter cleaner, serializer, de-serializer, and radar applications.
Software Support
We provide a library for the Buck 16 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The 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 the Buck 16 Click Board™.
Key Functions
buck16_enable_output
- Enable/Disable voltage output.buck16_set_potentiometer
- Set potentiometer resistivity.buck16_set_output
- Set output voltage.
Example Description
This example showcases ability of the device to control voltage output of device. Output voltage can range from 800 to 5500 depending of VIN. By default it will go from 800 to 3300 VIN==VCC.
void application_task ( void ) { log_printf( &logger, " > Setting output to 0.9Vrn" ); buck16_set_output( &buck16, 900 ); Delay_ms( 5000 ); log_printf( &logger, " > Setting output to 2.5Vrn" ); buck16_set_output( &buck16, 2500 ); Delay_ms( 5000 ); log_printf( &logger, " > Disable outputrn" ); buck16_enable_output( &buck16, 0 ); Delay_ms( 3000 ); log_printf( &logger, " > Enable outputrn" ); buck16_enable_output( &buck16, 1 ); Delay_ms( 3000 ); log_printf( &logger, " > Setting output to 1.5Vrn" ); buck16_set_output( &buck16, 1500 ); Delay_ms( 5000 ); }
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.Buck16
Additional Notes and Information
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.
mikroSDK
The Buck 16 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
