5pcs/lot DC-DC module power supply module XL6009 can raise pressure booster module super LM2577 DCDC booster

Our products are independent research and development and production, sophisticated technology, each products are through strict test before sent to the user. And can meet the demand of batch.32 V - 3.2 V input output highest 38 VOutput voltage range: 4 v to 38 v dc voltage continuously adjustable, high efficiency (96%) of the maximum output current for 4 a.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 higherDoes this module is adjustable booster module, can by adjusting the precision of modules above circle more adjustable potentiometerTo 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)
