6-24V to 5V DC-DC Buck Converter Down Module 3A USB phone charging Modules

New product introduction:

The maximum output current is 3A, long-term operation is 2.1A, and the margin is sufficient.

Adopting a new scheme design, the circuit design does not require electrolytic capacitors and tantalum capacitors (the life of electrolytic capacitors is short, and tantalum capacitors may explode). Three large-size solid ceramic capacitors (MCC) currently used in high-end circuits are used.

The ripple is very low. The 12V to 5V 3A is only about 10 millivolts. Many of the ripples in the industry have reached 500 millivolts or more, which will cause an invisible damage to the equipment, and seriously cause the equipment to work abnormally or damage. IPHONE is Very delicate.

The new solution uses synchronous rectification, and the circuit conversion efficiency is very high. The efficiency is as high as 97.5% when 6.5V to 5V 0.7A, and it is 94% when 12V to 5V 1A. Unlike some peers, the efficiency is only 60-70%. (The efficiency test removed the voltage drop of the input reverse connection protection diode and the fuse).

Use flat copper wire inductance to maximize conversion efficiency. Reduce heat generation.

The first TVS tube with output overvoltage protection function, 1.5A input fuse and 300W output 5V TVS tube for overvoltage clamp protection to protect USB devices.

The current USB step-down modules of the same industry have no overvoltage protection function, which poses a very big safety hazard to USB devices. If you think about the breakdown of the step-down module, 12V is directly added to your IPHONE, can your IPHONE be spared?

1. Using the latest USB identification circuit, it is perfectly compatible with IPHONE, most Android phones, and IPAD.

2. The short head gold-plated borderless USB has a long service life, which is by no means comparable to ordinary USB interfaces.

3. Output voltage indicator (red)

4. The input is equipped with a reverse connection protection diode, and the input positive and negative electrodes will not be damaged if they are reversed. (The test efficiency of our shop ignores the voltage drop of the input diode and the fuse)

5. Ultra-low quiescent current, quiescent current of 0.85 mA. It is connected to the car battery without a switch, and can be connected to the cigarette lighter line or the ACC power line.
