Housing for Mini Step Down Converter * Single Version * Double Version (e.g. for Arduino projects where 12V/5V/3.3V are required) * Double Version (with cable duct) https://www.ebay.com/itm/10-X-Mini-DC-DC-Converter-Step-Down-Module-Adjustable-1V-5V-12V-16V-for-RC-M6I7/173061772539?ssPageName=STRK%3AMEBIDX%3AIT&var=471817091656&_trksid=p2060353.m2749.l2649 !!!PETG or ABS (the converter becomes quite warm)!!! I made the double version so that if you have a 12V power supply, e.g. in an Arduino or NodeMCU project all three voltages 12V/5V/3.3V are available. ............................................................................................................................................. First measurement results show that the 1.8 output in the following constellation (in the housing) is quite realistic: in: 12.0V --> 9.0V/1.8A@~65°C (long term) Efficiency: 82.8% in: 12.0V --> 5.0V/1.8A@~67°C (long term) Efficiency: 82.6% in: 12.0V --> 3.3V/1.8A@~69°C (long term) Efficiency: 82.4% Have fun! SG Technical Parameters: Modular nature: non-isolated step-down Rectification: Synchronous rectification Input voltage: 4.75V-23V Output voltage: 1.0V-17V Output current: peak 3A, long time 1.8A Conversion efficiency: 96% (highest) Switching frequency: 340KHz Output ripple: 30mV (no load) Load regulation: ± 0.5% Voltage regulation: ± 2.5% Operating temperature: -40 ℃ to +85 ℃ Peripheral dimensions: 17 * 11 * 3.8 (L * W * H) (mm) Have fun, like, and share your makes...
