DC-DC Step-Down Module 6-24V to 5V 3A Car USB Mobile Phone Charger


1: Small Size and High Current output suitable to connect to solar cell or high voltage battery

2: Output Maximum current 3A , Long-running 2.1A, sufficient margin.

3: Design Circuit design does not require electrolytic capacitors and tantalum capacitors?Short life electrolytic capacitors, tantalum capacitors risk of explosion?. Now with the use of high-end circuit Large solid ceramic capacitors?MCC?3 .

Very low ripple, 12V turn 5V 3A only about 10 millivolts, many colleagues have reached a ripple 500 mV or more, the device will result in an invisible injury, a serious cause device is not working or damaged, IPHONE but very delicate .

4: The gram uses synchronous rectification The circuit is very high conversion efficiency, in turn 5V 0.7A 6.5V when High efficiency up to 97.5% , 12V turn 5V 1A, also reached 94%, unlike some peers efficiency is only 60-70%.?Efficiency Test to remove the input reverse polarity tection diode and fuse drop?.

5: The Flat copper wire inductance Maximize conversion efficiency. Reduce heat.

6: First the whole network with output overvoltage tection , There is 1.5A input fuse, there is 5V output of 300W TVS tube voltage clamp tection done to tect the USB device.

Now the buck peer USB modules do not have overvoltage tection, there is a very big security risk for USB devices, if you think about the step-down module breakdown, 12V directly on you, IPHONE above, your IPHONE can survive it?

7: Using the latest USB identification circuit, perfectly compatible IPHONE, the vast majority of Android phones, IPAD .

8: Gold-plated USB boundless short head , Long service life, not ordinary USB interfaces can be compared.

9: Output voltage indicator? red ?

10: Ultra-small size, 26.4 (L) * 15 (W) * 7.4 (H) mm, the whole network the minimum .

11: Enter with Reverse polarity tection diode Enter the positive and negative reversed not damaged,?Our test efficiency ignore the input diode and fuse drop?


12: Ultra-low quiescent current, quiescent current of 0.85 mA . Connected to the car battery without adding switches can be connected to the cigarette lighter line or the ACC power cable line.

QS-1205CBUL-3A power module

size: 26.4 (Long) * 15 (W) * 7.4 (H) mm

Click for Caution

Module parameters
