The Nano Power Click Board™ is a boost (step-up) DC-DC converter Click Board™ with extremely high efficiency and very low input voltage, aimed at the low power IoT market and battery-powered sensors and other devices. The input voltage can be very low: the conversion will start for voltages down to 0.95V, providing 5V to the connected load. Once started, the input voltage can drop as low as 0.4V, depending on the connected load.
The onboard DC-DC converter IC uses the pulse frequency modulation control scheme (PFM), which allows high efficiency and low power consumption for a wide range of output currents.
Software Support
We provide a demo application for Nano Power click 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 initializes and defines GPIO driver and performs control of device voltage.
For more details check the documentation.
Key Functions
void nanopw_enableDevice( const uint8_t state )- The function allows or blocks the input voltage (enables or disables device).
Example Description
The application is composed of three sections:
- System Initialization - Initializes ENABLE (RST) pin as an output.
- Application Initialization - Initializes the GPIO driver.
- Application Task - (code snippet) - Turns the device on for 5 seconds and then turns the device off for 10 seconds. Afterward, the output voltage starts to fall.
When the input voltage rises from 0.8V to 5.5V, the output voltage rises from 5.1V to 5.25V. When the input voltage is less than 0.8V, the output voltage is less than 5V.
void applicationTask()
{
nanopw_enableDevice( _NANOPW_ENABLE_DEVICE );
Delay_ms( 5000 );
nanopw_enableDevice( _NANOPW_DISABLE_DEVICE );
Delay_ms( 10000 );
}
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 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
This click board is supported by 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.
