6-24V to 5V3A 1xUSB DC-DC Buck Converter Module

Description

6-24V to 5V3A 1xUSB DC-DC Buck Converter Module

Introduction:
1: the use of new original US imports chip, is definitely not domestic chips, disassemble chip.
2: the maximum output current of 3A, 2.1A long run, the remaining amount.
3: the use of new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum capacitor explosion risk). Using the current high-end circuit on the use of large-size solid-state ceramic capacitors (MCC) 3.
Ripple is very low, 12V to 5V 3A only 10 mV or so, many ripples have reached 500 mV or greater, the device will cause an invisible injury, serious equipment will cause abnormal or damaged, IPHONE Very delicate.
4: the new program using synchronous rectification, circuit conversion efficiency is very high, in the 6.5V to 5V 0.7A when the efficiency of up to 97.5%, 12V to 5V 1A when it reached 94%, unlike the peer some efficiency only 60-70% The (Efficiency test eliminates the input drop resistance of the diodes and fuses).
5: the use of flat copper wire inductance, to maximize the conversion efficiency. Reduce calorific value.
6: the first network with the output overvoltage protection function, the input has a 1.5A fuse, the output 5V 300W TVS tube has done pressure clamp protection, protection of USB devices.
Now the peer USB buck module are not over-voltage protection, the USB device there is a very big security risk, you think if the buck module breakdown, 12V directly added to your IPHONE above, your IPHONE can be spared?
7: using the latest USB recognition circuit, perfect compatible with IPHONE, the vast majority of Andrews mobile phone, IPAD.
8: short side gold-plated boundless USB, long life, not ordinary USB interface can match.
9: Output voltage indicator (red)
10: ultra-small size, 26.4 (long) * 15 (width) * 7.4 (high) mm, the whole network minimum.
11: input with reverse polarity protection diode, input positive and negative lead and then will not be damaged, (OUR test efficiency ignores the input diode and fuse voltage drop)
12: ultra-low quiescent current, quiescent current 0.85 mA. Connected to the car battery without the need for switching, can be connected to the cigarette lighter line, or ACC power line.

Module parameters
Module nature: non-isolated step-down module (BUCK) synchronous rectification
Input voltage: DC 6-24V
Output voltage: 5.1-5.2V (can choose between 3.3-6V, the default delivery is 5.1V-5.2)
Output current: maximum 3A (full load please pay attention to heat), the actual test input 12V output within 2A without special heat treatment.
Conversion efficiency: up to 97.5% (6.5 rpm to 5V 0.7A) (short reverse polarity protection and fuse test value)
