XL6009 DC-DC Booster module Power Supply module output is adjustable Super LM2577 step-up Module

XL6009:

32V - 3.2V input output highest 38V

Output voltage range: 4V to 38V dc voltage continuously adjustable, high efficiency (96%) of the maximum output current for 4A.

Advantage: use double thickening black oil PCB with high quality, all use imported SMD aluminum electrolytic capacitors, high Q value power inductors. And every piece of plate passes through the strict technical test, test completely using separate antistatic protection bag packaging.

Note:

Does this modules relative to the LM2577 triode mode conversion efficiency is higher

Does this module is adjustable booster module, can by adjusting the precision of modules above circle more adjustable potentiometer

To change the output voltage. The highest output voltage is 38 v. Chronological booster, reverse-time step-down.

Does the module above marked GND (input), the IN + (input), GND (output), the OUT + (output)

Does working temperature:: industrial grade 40 to + 85 (-) (ambient temperature more than 40 degrees, please reduce power use, or enhance heat dissipation
