1PCS DC Step Up Converter Booster Power Supply Module Boost Step-up Board output 5V 3A 12V 1A

1PCS DC Step Up Converter Booster Power Supply Module Boost Step-up Board output 5V 3A 12V 1A

Descrtion:

1: Widely used

2: Small size, mini row booster board

3: Simple to use and easy to understand

4: Large area heat diation

5: High safety performance

Feature:

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 consumption standby, current le 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 diation is strengthened, the maximum measured value is 3.5A when the input is 4.2V and the output is 5V, 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 le 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 le than 1ma

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

Output rple: about 80MV

Reminder: The positive and negative of the power supply input cannot be reversed, and the main ch is squeaky 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 a thick wire when wiring. , The thin
