Description:
The voltage is pulled down to below 7V or less when the car starts, and as high as 15V or more at high engine speeds. It is difficult for electrical appliances working on 12V to work normally. This automatic buck-boost module solves this problem. No matter the input voltage is 5V, 12V or 32V, the output can be stabilized at 12V.
Features:
1. Ultra-wide input voltage range: 3.8V to 32V
2. Ultra-wide output voltage range: 1.25V to 35V (with automatic buck-boost, within the working range, any voltage input can be regulated for any voltage output)
3. Built-in 4A high-efficiency MOSFET switch, making the efficiency up to 94% (LM2577 current is only 3A)
4. Ultra-high switching frequency 400KHz, smaller ripple, smaller size (LM2577 frequency is only 50KHz)
5. The module adopts SEPIC topology circuit, which is a mature buck-boost solution
6. The main chip adopts XL6009, with ultra-high switching frequency 400KHz, smaller ripple and smaller size (LM2577 frequency is only 50KHz)
Instructions for use:
1. Connect to the power supply (5-32V), the power indicator light is on, and the module is working normally.
2. Adjust the blue potentiometer knob (usually turn clockwise to boost, counterclockwise Step down) and monitor the output voltage with a multimeter until the required voltage is reached.
3. Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally.
Precautions:
1. It is recommended to use the current within 2.7A when working for a long time. In order to ensure the stability of the output, please keep the minimum voltage difference of 1.5V.
2. The wiring is connected as shown in the connection diagram shown in the highlights. Please do not connect it in reverse. The wrong connection method may cause the power module to burn out.
Applications:
1. Vehicle regulated power supply, you only need to connect the input end of this module to the car cigarette lighter to supply power, you can adjust the potentiometer, and the output voltage can be adjusted arbitrarily between 1.25-30V to charge your mobile phone, MP3, MP4, PSP, etc. Powered by many devices, very simple and convenient.
2. Power supply to electronic equipment. When the equipment needs 3-35V power supply and the corresponding voltage power supply is in hand, this module can easily adjust the voltage to the required voltage and solve the problem.
3. System working voltage test, you can use this module to debug the working voltage range of various voltage test systems when doing projects, which is very easy and convenient.
4. Applications with unstable voltages such as automotive voltage regulation, solar photovoltaic power generation, and wind power generation.
