DC booster module 12V1A Efficient 3.7V lithium battery booster circuit board mobile power 5V3A

With the EN enable end, after the R3 resistance on the module is removed, EN is the enable pins, and the logic is high and effective (turning the voltage) low -off voltage (low power standby, the current is less than 1UA).High levels must not exceed 5V, and low levels should not be lower than -0.2V.

Input voltage: DC3-5V

Output voltage: 5V/9V/12V optional (there will be ilcope from 0.1 to 0.2V on the top and bottom)

Large current output electricity: 5V3.5A, 9V/1.3A, 12V1A (when enhanced the input of 4.2V output 5V when the heat dissipation is enhanced, the maximum 3.5A is measured. HoweverWire)

The output terminal cannot be connected to the emotional load like motors, motors, fans, etc.

If the output load is frequently activated or frequently fluctuated frequently, it is recommended to connect a large -capacity electrolytic capacitor at the output pad.

When the input terminal is a non -battery power supply, it is recommended to connect the electrolytic capacitance of large capacity on the input terminal.

Conversion rate: typical 95%(related to input and output parameters)

Static current is less than 1MA

Size: 14*22*4.0mm (length*width*height)

Output wave texture: about 80mv

Reminder: The power supply input is positive and negative cannot be connected, and the error is directly scrapped. The main chip is coquettish and afraid of static electricity. Try to ground the soldering iron as much as possible during welding. In additionThe thin electronic line cannot be achieved!
