This is a DC to DC 6-18V to 5V USB Output Step Down Power Charger Buck Converter

This mini DC-DC step-down voltage converter module supports 6-18V voltage input and 5V 3A output with input polarity reverse protection and output overvoltage protection, short circuit protection.

It adopts synchronous rectification technology to ensure ultra-high power conversion of up to 97.5% to take full use of your input power. On-board female type A USB port with identification circuit perfectly fit for iPhone iPad and Android smartphones as well as it can be useful to power or recharge any electronic gadget which requires 5V input power up to 3A

Features:

1. Non-isolated buck module (BUCK) synchronous rectification
2. Maximum Output Current: 3A MAX
3. Conversion efficiency: can up to 97.5% (6.5V step down to 5V 0.7A) (after short reverse protection and fuses test value)
4. Switch frequency: 500KHz
5. Output Ripple: 10mV around (12V to 5V3A) 20M bandwidth
6. High-quality USB port
7. Output voltage indicator (RED)
8. Small size, Compact Size
9. Input with reverse polarity protection diode, will not damage when input is connected incorrectly

Precautions:

1. please enhance heat dissipation when fully used for load output(i.e. 5V@3A with 18V Input).
2. For the ideal case (i.e. 5V@2A output with 12V Input) it does not need to enhance heat dissipation.

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

Package Includes:

1 x DC to DC 6-24V to 5V USB Output Step Down Power Charger Buck Converter
