Constant Current Voltage LED Driver Batery Charging Module LM2596 1.25~30V

Product Description

1.Charging for lithium battery: When the battery is under low voltage, it will be burned if we charge it with constant voltage. So we should charge it with constant current.

2.Driver high power LED: The power of one LED is limited, when we need higher brightness, we can use this module to achieve constant current drive for multiple

LEDs.Any other occasions which need constant current input.Output voltage: 7~35V    

Input voltage: 1.25~30VOutput current: Max 3ATransfer efficiency: 92%(Max)

Switching frequency: 150KHz Product size: 48mm(L)*23mm(W)*14mm(H)
