Nano Power click is a boost (step-up) DC-DC converter click 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 the 0.4V, depending on the connected load. The onboard DC-DC converter IC uses the pulse frequency modulation control scheme (PFM), that allows high efficiency and low power consumption for a wide range of output currents.
