Excellent Buck Driver – 18V 5W Cree Circuit Board for Flashlights (16.8mm*5.5mm) Reviews

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

Pros:
- very efficient
- programmable output current
- small and compact
- good build and quality
- easy to use
Cons:
- 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
Other:
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.
Bottomline:
I will order more of these and will recommend them to friends.
