DC5V/12V Step Up Boost Lithium Battery Circuit Board Module 1A 3.5A 18650 Lithium Power Bank Battery Charging PCB Booster Board

Features

1: Widely used

2: Small size, mini row booster board

3: Simple to use and easy to understand

4: Large area heat dissipation

5: High safety performance

With EN enable terminal, after the R3 resistor on the module is removed, EN is the enable pin, and the logic is high effective (turn on the boost) and low turn off the boost (low power standby, current less than 1uA). The high level cannot exceed 5V, and the low level cannot be lower than -0.2V.

Input voltage: DC3-5V

Output voltage: 5V/12V selectable

Large output current: 5V3.5A, 12V1A (when the heat dissipation is strengthened, the maximum 3.5A is measured when 4.2V is input and 5V is output, but it is recommended to be below 3A for long-term work. Please use thick wires for wiring, and it is recommended to use wires not less than 1.5 square)

The output end cannot be connected to inductive loads such as motors, motors, fans, etc.;

If the output load is frequently started or frequent large current fluctuations, it is recommended to connect a large-capacity electrolytic capacitor in parallel at the output pad.

When the input terminal is a non-battery power supply, it is recommended to connect a large-capacity electrolytic capacitor in parallel at the input terminal.

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

Quiescent current is less than 1ma

Size: 13*21*4.0mm (length*width*height)

Output ripple: about 80MV

Reminder: The positive and negative of the power supply input cannot be reversed, and the main chip is squeamish and afraid of static electricity. When soldering, try to connect the soldering iron to the ground reliably. In addition, because the module is small in size, but the current is large, you must use thick wires when wiring. , The thin electronic wire can't reach it!
