Transform Your System's Power Management with the Buck 23 Click Board™!
Tired of inefficient and unreliable power converters? Upgrade to the Buck 23 Click Board™! This compact add-on board features the MAX20010C, a fully-integrated, high-efficiency, synchronous, step-down converter from Analog Devices. With its ability to step down voltage from its input to its output, this board is perfect for point-of-load and post-regulation applications.
Enjoy peace of mind with the MAX20010C's 6A continuous output current over a wide input supply range from 3V to 5.5V. You can also count on its ±2% output voltage accuracy and efficient operation over a configurable output voltage load range from 0.5V to 1.58V. Additionally, the MAX20010C includes programmable soft-start, overcurrent, and overtemperature protections.
The Buck 23 Click Board™ is also incredibly easy to use. It comes fully tested and ready to be used on a system equipped with the mikroBUS™ socket. And with its support for a mikroSDK compliant library, software development is a breeze! Simplify your power management and transform your system with the Buck 23 Click Board™!
Software Support
We provide a library for the Buck 23 Click Board™ as well as a demo application (example), developed using MikroE compilers. The demo can run on all the main MikroE development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager(recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Buck 23 Click Board™ driver.
Key functions
-
buck23_set_vstep
This function sets the voltage output step to 10mV or 12.5mV. -
buck23_set_vout
This function sets the voltage output. -
buck23_get_pg_pin
This function returns the PG (power good) pin logic state.
Example Description
This example demonstrates the use of the Buck 23 Click Board™ by changing the output voltage.

uint8_t status;
if ( BUCK23_OK == buck23_set_vstep ( &buck23, BUCK23_VSTEP_10 ) )
{

log_printf ( &logger, " ------------------------------------" );
}
for ( vout_mv = BUCK23_VOUT_MIN_VSTEP_10; vout_mv <= BUCK23_VOUT_MAX_VSTEP_10; vout_mv += 50 )
{

{

vout_mv -= 50;
}
Delay_ms ( 1000 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager(recommended), downloaded from our LibStock™ or found on MikroE Github account.
Other MikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Buck23
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, 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 MikroE compilers.
MIKROSDK
The Buck 23 Click Board™ is supported with mikroSDK - MikroE 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.
