2. Input: IN+ input positive IN- input negative
3. Output: OUT+ output positive OUT- output negative
4. Static power consumption is only about 6mA.
5. Connection: Welding, plus pin can be directly soldered after the PCB.
6. Short circuit protection: current limiting, thermal protection, self-recovery.
7. Non-isolated step-down (BUCK) switching regulator.
8. Short circuit protection: Current limiting, self-recovery
9. Potentiometer adjustment direction is as Clockwise (increase) and Anti-clockwise (decrease)
10. Non-synchronous rectification

DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module cant output more power than its inputs.

This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 1.5A depending on input/output voltage settings with 1A available with most settings.

Since it is a boost converter, the input voltage must be lower than the output voltage.

The device is able to use low ESR bulk ceramic capacitors rather than electrolytic caps which avoids long-term aging concerns and contributes to the compact packaging.

The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard.

The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard.

The module has a single-turn potentiometer for adjustment of the output voltage.

Turning the pot CW decreases the output voltage while turning it  CCW increases the output voltage.

The upper limit of the adjustment range will depend on the input voltage and the load.  With a 9V input for instance, at 1A, the upper voltage limit will be approximately 20V.

These are compact boards with 4 solder pads for making connections.

1. VIN+ =      Input Voltage

3. VOUT+ = Output Voltage
4. VOUT- =  Ground.  Connected to VIN- on the module.

1. The input voltage should not exceed the maximum input voltage.
2. Peak current output current is not more than 2A for input & output.
3. Please be noted that the output voltage should be higher than the input voltage.

1. It’s efficient by up to 93%.
2. It can source a good amount of current.
3. It is an inexpensive converter module.
4. It’s simple to adjust to get your desired increase in voltage.

Most of the sensors, Development Boards like Arduino, Raspberry Pi and PIC Controllers work on either 5V or 3.3V most commonly available battery we have with us is 9V or 12V lead acid batteries so it is essential that we supply the components with correct voltage otherwise they may misbehave or simply not work at all. Also, fluctuations in power supply will result in errors and garbage data from the sensors. It may also corrupt the SD card on which you are writing the data or cause your program to misbehave. To deal with this problem we can use this Ultra-Small Size DC-DC Buck Converter module which can step down the DC voltages from upto 28V to 5-20V. The output voltage of this module can be adjusted too which means you can control the output voltage of this module. The main advantage of this module is that it can provide a high output current of upto 3A so that you can even connect small motors to it without thinking much but keep an eye on heat dissipation of the module.
