Step Down 3 Click is a compact add-on board that steps down the voltage from its input to its output. This board features the ST1PS03, a nano-quiescent miniaturized synchronous step-down converter with a load switch from STMicroelectronics. The ST1PS03 can provide up to 400mA output current with an input voltage ranging from 1.8V to 5.5V, specifically designed for applications where high efficiency is crucial. It also embeds a controlled switch accessible from auxiliary channel input to supply a subsystem, output voltage from 1.6V to 3.3V set using three digital control inputs, and a Power Good signal to indicate stabilized output voltages.
We provide a library for the Step Down 3 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Step Down 3 Click driver.
stepdown3_cfg_setup
Config Object Initialization function. stepdown3_init
Initialization function. stepdown3_enable_device
This function enables the auxiliary output (VOUT_AUX) by setting the AUX pin to HIGH logic state. stepdown3_enable_aux_output
This function disables the auxiliary output (VOUT_AUX) by setting the AUX pin to LOW logic state. stepdown3_set_output_voltage
This function sets the output voltage by setting the D2, D1, and D0 pins to a desired state. This example demonstrates the use of Step Down 3 click board by iterating through the entire output voltage range.
The demo application is composed of two sections :
Initializes the driver and logger, then enables the click board and disables the auxiliary output.
Changes the output voltage every 3 seconds and displays the set voltage output value on the USB UART.
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.

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. UART terminal is available in all MikroElektronika compilers.
