Buck 5 Click Board
Buck 5 Click Board
The Buck 5 Click Board™ is a high-efficiency buck (step-down) DC/DC converter, which can provide digitally adjusted step-down voltage on its output while delivering a considerable amount of current. Buck 5 Click Board™ accepts a wide voltage range on its input - from 5V to 30V. The output voltage may be adjusted via the SPI interface, in the range from 0.9V to approximately 5.5V. This Click Board™ utilises the MAX17506, an integrated high efficiency, synchronous step-down DC/DC converter with internal feedback compensation, from Maxim Integrated. In addition, the MAX5401 digital potentiometer with SPI Interface is used on the feedback loop allowing digital control of the output voltage.
Software Support
We provide a library for the Buck 5 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
Initializes and defines SPI driver and driver functions which can use for power supply control. This library offers a choice to set maximum output voltage, which can be between 1V and 5.5V. For more details check the documentation.
Key functions :
void buck5_powerOn() - Function for power ON chip.
void buck5_reset() - Function for reset chip.
void buck5_setOutputVoltage(uint8_t voltage) - Function for setting maximum output voltage.
Example Description
The application is composed of three sections :
- System Initialization - Initializes SPI module and AN pin, RST pin, CS pin as OUTPUT and PWM pin as INPUT.
- Application Initialization - Initializes driver init, power On-chip and reset Buck 5 Click Board™.
- Application Task - (code snippet) - Sets 3 different output voltage every 2 seconds.
void applicationTask() { buck5_setOutputVoltage(BUCK5_VOLTAGE_1500mV); Delay_ms( 2000 ); buck5_setOutputVoltage(BUCK5_VOLTAGE_3000mV); Delay_ms( 2000 ); buck5_setOutputVoltage(BUCK5_VOLTAGE_4500mV); Delay_ms( 2000 ); buck5_setOutputVoltage(BUCK5_VOLTAGE_3000mV); Delay_ms( 2000 ); }
The full application code and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- Conversions
- SPI
- UART
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ 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 5 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.
