Electrical parameters:

Input: DC 3.2V to 35V (input voltage must be more than the output voltage can not be higher than boost 1.25v.)

Output: 1.25V to 30V DC voltage is continuously adjustable, high efficiency and maximum output current of 3A.

Features: All solid capacitors using SANYO, 36u thick circuit boards, high-Q inductors with high power output LED indicator

Size: 41 (L) * 20 (W) * 14 (H) mm (including potentiometers) Taobao minimum with locating hole with LED indicator DC-DC


Access to power (3-35V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage.


1. welding, welded directly to the power line input (output) port;

2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.

Application examples:

1. The vehicle power supply, only need to enter this module termination point the car cigarette power supply, you can adjust the potentiometer, the output voltage can be adjusted in 1.25-30V, for your phone, MP3, MP4, PSP charging many devices powered, very simple and convenient.

2. The power to the electronic device when the device needs 3-30V power supply voltage corresponding to the hand while using this module you can easily put the voltage to the desired voltage and solve problems.

3. The system voltage test can be used to make this project a variety of debugging module voltage test system operating voltage range, very easy and convenient.
