Buck 3 click is a very advanced synchronous step-down (buck) converter, which is designed to deliver noise and ripple-free voltage to highly sensitive applications, such as FPGA and high-performance DSP platforms.
We provide a library for the Buck3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Buck3 Click driver.
void buck3_cfg_setup ( buck3_cfg_t *cfg );
BUCK3_RETVAL buck3_init ( buck3_t *ctx, buck3_cfg_t *cfg );
void buck3_default_cfg ( buck3_t *ctx );
void buck3_set_device_state ( buck3_t *ctx, uint8_t state );
uint8_t buck3_get_power_good ( buck3_t *ctx );
Demo application checks the status of the device and the voltage.
The demo application is composed of two sections :
Configuring clicks and log objects. Settings the click in the default configuration.
Sequentialy, each one second, checks the status of the Buck 3 Click and if the overvoltage detected or device is under thermal shutdown it logs a message on the USBUART.
Open Drain Power Good Indicator, it is asserted low if output voltage is out of PGOOD threshold, Overvoltage or if the device is under thermal shutdown, EN shutdown or during soft start. Once the FB pin voltage is between 93% and 107% of the internal reference voltage (VREF) the PGOOD is pulled high.
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
