DC-DC Step Up Step Down Auto Boost Buck Voltage Power Supply Converter Module LM2577S + LM2596S 4-35V to 1.25-25V Adjustable

Overview:

• Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module
• Input Voltage: 4-35V
• Output voltage: Continuously adjustable( 1.25 -25V unload adjust)
• Output current: 3A Max(If more than 15W, please install the heat sink)
• CC range: 0-2A (adjustable)
• Revolving light current: CC value * (1%-100%), default is 0.1 times
• Minimum voltage difference: 2V
• Output power: natural cooling 15W
• Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency)
• Operating Temperature: Industrial (-40? to +85? ) (ambient temperature more than 40?, lower power use, or add heat sink)
• Full load temperature rise: 45?
• Indicator: CC indicator is Red, charging indicator is Red, charging completed the indicator is Blue.
• Output short circuit protection: Yes, constant current.
• Connect method: Can solder on the PCB with wire directly
• Input: IN+ input Positive is, IN- input negative
• Output: OUT+ output is positive, OUT- output negative
• Module Size: 50 x 37 x 13mm

Instructions:

• Input: IN + input positive level, IN- input negative
• Output: OUT + output positive level, OUT-output negative
• Wiring: leads directly soldered to the PCB
• Adjustment method: first correct the input power (between 4-35V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise)

Notice:

• Please don't connect the GND of OUTPUT to GND of INPUT!!!!
