6-24V Input to 5V USB 2A Car USB Charger Module DC-DC Buck Step-Down Converter

  • Sale
  • Regular price $5.49

This 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.


  • 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 voltage 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: Yes, 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)
