Product Description:

It is a 5W Buck Converter/Voltage Regulator/Adapter, Input Voltage: DC 6.5~24V ( if input greater than 15V, output current 0.8A), Output voltage: DC 5V, Application: DIY Power adapter, industrial equipments, electronic equipment, Communications Equipment etc.


  • Module Properties: non-isolated step-down module (buck)

  • Rectifier mode: synchronous rectification

  • Input Voltage: DC 6.5~24V ( if input greater than 15V, output current 0.8A)

  • Output voltage: DC 5V ( Precision ±1%)

  • Output power: 5W

  • Recommended input and output capacitors: input capacitance 10UF (ceramics), the output capacitor 22UF (ceramic)

  • Maximum capacitive load: 1000UF

  • Output Current: 1A

  • Conversion efficiency: input voltage 6.5V 94% (highest), input voltage 20V 85% (minimum)

  • Operating temperature: industrial-grade (-40°c to +85°c) (85°c Output current 0.5A)

  • The maximum case temperature at working: 100°c

  • Full load temperature rise: 50°c

  • Load regulation: ± 0.5%

  • Voltage Regulation: ± 0.5%

  • Output ripple: 1A load current (typical application circuit, the input ceramic capacitors 10UF, output ceramic capacitors 22UF)

  • Input 6.5V output ripple 13mV

  • Input 12V output ripple 30mV

  • Input 20V output ripple 45mV

  • Bandwidth: 20M

  • If you need to lower the ripple, please install LC filter at the output

  • Dynamic response speed: 5% 200uS

  • Short circuit protection: current limit (3A), Self-Recovery

  • Over-temperature protection: 150°c

  • Static Current: 7~20 mA (The higher the input voltage, the higher of the Static Current)

  • Input reverse polarity protection: None

  • Wiring: Welding, the SIP-3 package, compatible with the LM7805.


  • Integrated within the filter capacitor, Even without an external capacitor, the item can work properly.

  • In order to lower the output ripple, please install filter capacitor at the input and output port.
