Mini DC-DC Boost Step Up Converter 3.7V to 5V / 8V/ 9V / 12V

3.7V to 12V Mini DC-DC Boost Step Up Converter Board Module 5V/ 8V/ 9V 12V Output is a DC-DC Boost step-up converter module that is used to step up the voltage. The voltage boost converter module that provides 3.7V DC stable voltage output at various input ranges between 3.7V to 12V. This small tiny circuit boosts the voltage level and provides the amplified stabilized 5V/ 8V/ 9V 12V output. For the different input ranges, it consumes a different amount of current to produce a balanced output.

Features :

• The maximum output current reaches 1A.
• Low power consumption.
• The LED indicator can be turned off by the pad next to it.

Basic parameters:

• The output voltage can be set to 5V/8V/9V/12V, the default is 12V.
• Input voltage range: 2.5V-5VOUT. The input voltage must be lower than the set output voltage.
• Output capability: When inputting 3.7V lithium battery, it can output 5V1A, 8V0.5A, 9V0.45A, 12V0.3A.
• When inputting at 5V, it can output 8V0.7A, 9V0.7A, 12V0.5A.
• When the default 12V output, the LED indicator consumes about 1mA.
• If the indicator is turned off, the input current is ＜1mA at no load.

Voltage setting description:

• The front side of the PCB can be seen with the words A and B. Use the soldering iron to change the pad pass next to the character.
• The output voltage can be changed by breaking. In the following table, 0 indicates that the pad is disconnected, and 1 indicates that the pad is connected.

• The pad next to the LED indicator can also be turned off to turn off the indicator.
