    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)

    • 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.
