Product description
With the EN enable end, after removing the R3 resistance on the module, EN is the enable pin, and the logic is high effective (on boost voltage) and low off boost voltage (low power standby, current less than 1uA). High level should not exceed 5V, low level should not be lower than -0.2V.
Input voltage :DC3-5V
Output voltage :5V (there will be positive and negative 0.1 to 0.2V voltage up and down)
Output current :5V3.5A, when strengthening heat dissipation input 4.2V output 5V measured maximum 3.5A, but long-term work is recommended below 3A, please use thick wire, it is recommended to use not less than 1.5 square line)
The output end can not be connected to inductive loads such as motors, motors, fans;
If the output load is frequently started or has frequent large current fluctuations, it is recommended to connect a large-capacity electrolytic capacitor to the output pad.
If the input end is a non-battery power supply, connect a large-capacity electrolytic capacitor to the input end.
Conversion rate: Typical 95%(dependent on input/output parameters)
The static current is less than 1ma
Size: 14*22*4.0mm(L * W * H)
Output ripple: about 80MV
Warm tips: the positive and negative power input can not be reversed, the wrong connection is directly scrapped, the main chip is delicate and afraid of static electricity, and the soldering iron is reliably grounded when welding, in addition, because the module is small in size, but the current is large, so the wiring must use a thick wire, the fine electronic wire is not up to it!
