  • Excellent Buck Driver

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month


    - very efficient

    - programmable output current

    - small and compact

    - good build and quality

    - easy to use


    - price could be lower

    - not suitable for use when supply voltage is less than emitter voltage

    - output current needs to be lowered as it may overstress XRE and XPE power LEDs

    - low efficiency with low output currents


    This is one of the best buck drivers in DX. Output current is easily changed by replacing the sense resistor with an appropriately valued resistor. I am using these to drive 2 power LED's for upgrades to some of my emergency lighting systems. I've successfully used them to drive 2 XRE Q5's at 500mA each and will use them to drive 2 LBW041050B 1W LED emitters for another project. This driver is good for DIY LED lamp projects where supply voltage is around 6V.


    I will order more of these and will recommend them to friends.
