DC – DC 6-24V to 5V USB Output Step Down Power Charger with Adjustable Buck Converter

DC – DC 6-24V to 5V USB Output Step Down Power Charger with Adjustable Buck Converter

This USB Output Step Down Power Charger accommodates a 6-24V voltage input and delivers a 5V 3A output, complete with input polarity reverse protection, output overvoltage protection, and short circuit protection.

 

Utilizing synchronous rectification technology, it achieves an ultra-high power conversion efficiency of up to 97.5%, maximizing the use of the input power. The onboard female type A USB port, equipped with an identification circuit, is ideally suited for iPhones, iPads, and Android smartphones. It is also capable of powering or recharging any electronic device that requires a 5V input power at currents up to 3A.

Note:

• The Module has Output short circuit protection, but please do not a short circuit for a long time to avoid damage due to overheating.
