Feature:
1, DC input voltage range: 3.2V to 46V (input voltage to the output voltage must be higher than 1.5V. Cannot boost)
2, the output voltage range: 1.25V to 35V DC voltage continuously adjustable, high efficiency (up to 92%) the maximum output current is 3A.
3, the input end with reverse connection protection, positive and negative reverse module will not burn.

Usage:
1, access to power (3.2V-40V), the power indicator light, the module is working properly.
2, adjust the blue potentiometer knob (generally clockwise boost, counterclockwise Buck) and the multimeter is used to monitor the output voltage to the voltage you want.

Attention:
Long time work is recommended in the current use of less than 2.5A, plus the heat sink (10W above output); due to the buck module, in order to ensure the output stable, please keep the minimum 1.5V pressure difference.

Application:
1, vehicle regulated power supply, only need the module input terminal is connected to the car cigarette mouth power supply can adjust potentiometer, the output voltage can be in 1.25-30V can be adjusted arbitrarily, for your mobile phone, MP3, MP4, PSP charging many power supply equipment, very simple and convenient.
2, to the electronic equipment power supply, when the equipment needs 3-35V power supply and the corresponding voltage power supply, with this module can be easily transferred to the voltage required to solve the problem.
3, the system operating voltage test, the project can use this module to debug a variety of voltage testing system operating voltage range, very easy and convenient.
