DIY CAT4101 DRIVER

Thankfully, I found another comparable source, and they offered the XP-Gs R5 at just a slightly higher price! I will also be having code made for the Arduino, and will share once that is done Find More Posts by reefocean. It is also contains a 12 volt regulator and is mounted to a small fan cooled heatsink. San Jose, CA Posts: Unlike most switching drivers buck, boost, etc , the CAT needs a low external parts count, no inductor, and requirements for trace length and placement of external components are much more lax. Be happy to discuss this

Ideally I want to use v analogue dimming because I have a controller that uses this but if I had to, Cat411 could work, I would just have to buy a new controller. Your latest build or DWZM’s initial build? A buck driver would improve the efficiency a lotbut that’s all. The fixed resistor protects against accidentally setting zero ohms on dih trimpot, and potentially destroying the CAT and your LEDs.

Only the current sink like the TLC needs special treatment: You’ll just need to calculate the correct resistance.

Because cta4101 this, I decided to go the DIY route and build my own design to save some money. Please enter your desired user name, your email address and other required details in the form below. Image resizer by SevenSkins. After that, I’d recommend a good heft TVS transient voltage suppressor diode to clamp the positive xiy voltages. Well, I’m going to put my stash of ‘s to use soon ish, probably Thanksgiving when I get around to the lighting part of my new build.

Note that passwords are case-sensitive. The SMT parts weren’t as bad as I thought- just needed a steady hand and the good ‘ol solderwick for mistakes! AQ will of course preserve the links back to your blog.

But I want to build the driver myself because all the drivers I have seen duy are expensive.

Require a single 5V input should be easy, since the analog dimming is designed for 5V signal anyway to power the opamp and set the cutoff voltage or B.

I put together the circuit and cxt4101 doesn’t work!

Yeah, figured that much, wishful thinking. Add a Comment Sign in to comment.

Thanks for the info guys. So from here we have 2 ways of addressing this: This DIY route worked well until my designs became complicated enough that these methods were no longer feasible. Anyone know where I can find any schematics? The last pages hold the answer.

Unfortunately, my order was automatically cancelled by the source duy. It is also contains a 12 volt regulator and is mounted to a small fan cooled heatsink.

There is also expresspcb if Eagle is to complex. Here’s what they look like reference to Sg 20cts – note the really small die!

Also, if there has been a dimmer module designed for the drivers, Id appreciate the docs on that too I am working with kcress on trying to find a solution, but if that doesn’t work out I might need to buy a new supply. Analog dimming requires 5V reference voltage to power OpAmp, set low voltage limit etc.

Driving 3 white LEDs in series with just a resistor from 12 is verty effcient and there’s not much advantage in using a driver. This will appear once only per visit to AQ. Nothing special is needed, since you mentioned you have an arduino. Diyy most recent system consisted of 6 dly PC bulbs for a ct4101 of watts.
