It's LM2596HVS Not LM2596S Chip, please know it
Type /name: LM2596HVS DC-DC step-down module
Input Voltage: 4.5V ~ 53V
Output Voltage: 3V ~ 40V
Output Current: 3A (max)
Conversion efficiency: 92% (the highest)
Output Ripple: <30mV
Switching frequency: 150KHz
Operating Temperature: -45 ~ +85
Size: 43mm * 21mm * 14mm (L * W* H)
IN-IN + inputPositiveInput Negative!
Positive outputOUT +OUT-output negative
Input voltage range: DC 4.5V to53V (inputvoltagemust be greater thanthe outputvoltageto 1.5V or 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 than 2.5A (or outputpower greater than10W) to work long hours, please addheat sink.
