Description:
The module uses a high-quality lm2596 chip, with high efficiency (up to 92%), low calorific value, and can easily carry a current of more than 3A (for a short time). For long-time operation, it is recommended to use a current of less than 2.5A, and add a heat sink (more than 10W output).
This module uses machine mountings and reflow soldering. At the same time, each module goes through two hours of aging test before shipment to ensure high reliability.
As for the on-board regulated power supply, you only need to connect the input end of this module to the car cigarette lighter for power supply, you can adjust the potentiometer, and the output voltage can be adjusted at 1.25-30v. It is very simple and convenient to power your mobile phone, MP3, MP4, PSP charging and many other devices.
Supply power to electronic equipment. When the equipment needs 3-30V power supply and the hand corresponds to the voltage power supply, this module can easily adjust the voltage to the required voltage to solve the problem.
For the system working voltage test, this module can be used to debug various voltage test system working voltage ranges when doing projects, which is very easy and convenient.
