Buck 9 Click Board
Buck 9 Click Board
The Buck 9 Click Board™ is a high-efficiency step-down converter that provides a highly regulated output voltage derived from the connected power source, rated from 4V to 36V. The regulated output voltage can be selected between two values: 3.3V and 5V. These are voltage values that are most commonly used in many embedded designs. Buck 9 Click Board™ is based around an integrated DC-DC converter, labelled as MP9943. Due to its high efficiency, MP9943 allows the Click Board™ to easily deliver up to 3A of current. The MP9943 is very reliable, offering over-current and under-voltage protection, as well as a thermal shutdown
Software Support
We provide a library for the Buck 9 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
Library carries functions related to GPIO pins control of the Buck 9 Click Board™. The library includes function for enable or disable device.
Key Functions
void buck9_deviceEnable(uint8_t state)
- Function for enable or disable device.
Example Description
The application is composed of the three sections :
- System Initialization - Sets PWM pin as OUTPUT.
- Application Initialization - Initialization driver init and disable device.
- Application Task - (code snippet) - Enable and Disable device every 5000 ms.
Application Task - Predefined characters are inputed from the serial port. Depending on the character sent the signal frequency, waveform or amplitude will be changed.
void applicationTask() { buck9_deviceEnable(_BUCK9_DEVICE_ENABLE); Delay_ms( 5000 ); buck9_deviceEnable(_BUCK9_DEVICE_DISABLE); Delay_ms( 5000 ); }
The full application code, and ready to use projects can be found on our LibStock page.

Additional Notes and Information
Depending on the development board you are using, you may need a 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 9 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.
