HOW DOES IT WORK?
Nano Power 3 Click is based on the RPL-3.0-R, a buck converter with an integrated inductor from Recom Power. This thermally-enhanced converter uses, as input, voltage from 4 up to 18VDC, thus allowing 5V and 12V supply rails to be used. It's fully protected against continuous short circuits, output overcurrent, or over-temperature faults. To set the output voltage on the VOUT terminal, the Nano Power 3 Click uses the MAX5419, a 256-tap nonvolatile digital potentiometer from Analog Devices. This potentiometer features the power-on recall of the wiper position from nonvolatile EEPROM memory. The nominal resistance of this potentiometer is 200kΩ, and together with an onboard resistor makes a voltage divider that feeds the feedback input of the buck converter. You select the output voltage value by setting the resistance value on this potentiometer.
Nano Power 3 Click uses a standard 2-Wire I2C interface of the MAX5419 to communicate with the host MCU, supporting Fast mode and data rates of up to 400Kbps. The I2C address can be set over the ADDR SEL jumper with 0 selected by default. In addition to the digital potentiometer control, you can also control the buck converter by turning it OFF via the CTR pin. The PG pin serves as the buck converter Power Good condition output, which interrupts the host MCU according to meeting one of the overvoltage or undervoltage thresholds and sink current capability. The buck converter's output voltage can be read over the AN pin of the mikroBUS™ socket.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
