Controlled DC-DC Step-Up Converter Maker The MH-Z14A from Winsen isHave you needed to power a small sensor with 12 or 24V but only had 3. 3V or 5V available? Maybe you need to really reduce your power consumption and running the sensor all the time will consume too much power? Then this simple enable line controlled DC DC step up converter might be useful for you! The step up converter is an off the shelf DC DC converter board using the MT3608. This can take an input voltage of 2 24V DC and supply an output voltage
