30W high power and wide voltage lifting pressure module, performance far beyond LM2596, LM2577. Output voltage can be higher or lower than the input voltage.

 

Adjustable version
Weight: 13g
Appearance size: 48*26*13mm (length * width * height)
Input voltage range: 5.0-25V
The output voltage range: 0.5V-25V
Continuous output current: 3A (max)
Continuous input current: 3A (max)
Input / output power: 30W (max)

Input / output current: Calculation of rated condition of input / output current according to the conservation of power (Uin*Iin* =Uout*Iout)

 

IN+: input anode IN-: input cathode OUT+: output positive OUT-: negative: output enable switch: disconnect the short cap module output.

No input reverse connection protection, reverse connection will burn, please note that when using the polarity
Output short circuit module will automatically stop output, to swap enable switch short-circuit cap can be restored
Module at the start and off load is easy to occur when the output voltage transient exceeds the preset voltage, so not suitable for device voltage sensitive
