IN-IN + inputPositiveInput Negative!

Positive outputOUT +OUT-output negative

Input voltage range: DC4.5V to53V (inputvoltagemust be greater thanthe outputvoltageto1.5Vor morehigh.Could notboost)

Output voltage range: DC3Vto 40Vvoltage is continuously adjustable, high efficiency(up to 92%)the maximum outputcurrent of3A.

Measured12V input, 5Voutputcurrent is 1Aload regulationrate of less than1%

Note: This is thestep-down module, the input voltagemust behigher than the outputvoltage.

Outputcurrent is greater than2.5A (or outputpower greater than10W)to work long hours, please addheat sink.
