6-24V TO 5V 3A USB DC-DC BUCK STEP-DOWN CONVERTER

This is a small and handy 5V 3A USB DC-DC Buck Step-Down Converter Power supply module that can handle voltage from 6-24V. With a USB port end connector it is easy to use for charging mobile phone, powering single board computers like Raspberry Pi and other eletronics projects. It can handle up to 3A of continuous current.

Features / Specifications

The max output current is 3 Amps
New design, 3 solid state ceramic capacitors(MCC), more safe and low ripple
Synchronous rectification, High efficiency, 6.5V to 5V 0.7A can up to 97.5%, 12V to 5V 1A can up to 94%
Flat copper inductor, improve conversion efficiency
With output overvoltage protection. There is 1.5A fuse, output 5V have 300W TVS tube protect your USB device
Using the latest USB identification circuit, perfectly compatible with IPHONE, the most of Android phones, IPAD etc
High quality USB port
Output voltage indicator (RED)
