[Current Regulator] First PCB and Microscope Lightning

Hello, It has been sometimes I didn’t write anything here. I had plenty of projects and things to do ;) At the beginning of this week I finally receive my seeedstudio (a little advertisement for their great quality services !) and as usual it was perfectly synchronized with something I need ! I receive my […]

[Current Regulator] Final Prototype and ESR considerations

Introduction First news the final prototype is working, with all modifications done. 2 days before receiving my Chinese LED the light bulb of my desktop magnifier died in some mysterious ways, simple coincidence or an Enigma of the Mystical… We will never know ;) By the way my LED current regulator seems to be right […]

[Current Regulator] Working « prototype » (en)

I have a working prototype of the current regulator. If you took a look at the previous post, I implemented a totem pole because of some stability problem on the Mosfet switching. It’s always a good idea to drive Power Mosfet with this kind of circuitry if you use an uC. But in that case […]

[Current Regulator] Do you need some Spice in your Design (en)

Yes ! You need it. LTSpice Introduction and schematic A little feedback about Spice simulation, at first I was a little skeptical. My first spice schematics was not that good because of « bad » models (understand Ideal models), but more recently at my work I had to use it before prototyping some « complex » analog board (Fet, […]
