6-24V Input to 5V 2A Output USB Charger Module DC-DC Buck Step-Down ConverterThis step-down (buck) power supply module converts its input voltage of 6V to 24V to a fixed 5V USB output at up to 2A continuous output current. It is ideal for providing a regulated 5V USB output to charge your iPhone, Android phone, tablet or any other USB-powered device. It can be powered from a 6V, 9V, 12V or 24V battery, solar panel, wind generator or other power source. Specifications: Module Properties: Non-isolated buck (step down) synchronous rectification converter module Input voltage: Variable DC 6-24V Input connectors: Solder pads Output voltage: Fixed 5.0-5.2V Output connector: USB Output current: 2A continuous maximum NOTE: With input voltages less than 10V, the maximum output current is limited to ~1A. Operation above 1A output current requires >10V input voltage. At input voltages above 12V @ 2A continuous output current, please enhance heat dissipation with additional heatsinking or forced-air cooling. Conversion efficiency: Up to 97.5% at 6.5V input 0.7A, 94% at 12V input 1A output. Switching frequency: 500KHz Output ripple: 10mV at 12V input 2A Output indicator: Red LED Operating temperature: Industrial grade (-40 degree to + 85 degrees, at higher ambient temperature, the output power may need to be derated) Output overvoltage protection: Input 1.5A fuse, output 300W TVS clamp protection Static current: 0.85 mA Load regulation: +/- 1% Voltage Regulation: +/- 0.5% Dynamic response speed: 5% 200uS Output short circuit protection: Yes, but please do not leave short circuited for an extended period Input reverse polarity protection: Yes, reverse polarity protection diode Dimensions: 26mm x 14mm x 8mm (L x W x H) Package includes: 1x USB DC Converter 5V 2A Out 6V-24V in Printed installation and operation instructions Ships in 1 business day from our Colorado office for quick delivery.Expand your DIY and Arduino-compatible development with these other Arduino-compatible development boards, shields and modules from Envistia Mall.
