Has anyone made an LED driver based on LM3463 6 channel driver IC?

That's what I thought,....I'll go look again. I put one driver together for practice to see how it would go(not the whole board). Your step by step directions were perfect. The only part that gave me some trouble were the copper heatsinks. I couldn't get them to heat up enough with me soldering iron,...had to get out the Weller 8200 and still had a little trouble getting that big hunk of copper hot enough. lol. Once I get the diodes straight I'll be slamming. :D
 
Hey O2,...one more question for you. On my board, there is 5 of each part except the 47uf cap. I see that they all have one side going to gnd. and their other sides all go to the v in pin on the 6211, and they are all interconnected,but on your 5up board that Krazie just posted there are 5 47uf caps.am I good?---Rick

Rick- You're fine. The 47uf caps are for noise filtering and pretty much complete overkill. They're a relic leftover from the Allegro suggested circuit design. CONTINUE SOLDERING

That sir is bloody brilliant and almost exactly what I am trying to put together (see my PM :) ). You sir, are a machine!

I almost peed reading your Cheech & Chong reference! for some reason I pictured you younger than myself but I think we were cut from the same clothe! LOL

Thanks for everything man! Krazie:jester:

Dude! I'm going to be 47 this year. I was only 10 when "Up in Smoke" was in theaters LOL.
I'm stuck at work today, and I actually have to "work" this time. I'll get to your PM sometime tonight. LOL

I'm only a year off you. LOL

Whenever you get a second is fine. Just glad to have your help!
 
Looks nice bigguy,...that O2,....he'sss the man. I see there is a rtc on board, what are you using for a screen to set your leds on/off, fan start ups ect?---Rick

Does he have the varied amperage models O2?...is that what the 6 pin headers are for?---Rick

Yes- he's got the choice of 300, 700, 1000, or 1400ma per channel :beer:

thanks dude :)

will get 2 orded they have none but some on eBay but 3 weeks :(

are these needed for the fans ?

need to hook up to pc and figure out the Adriano side of stuff :)

anybody else got one of these and any example code :)

thanks again 02

Yes- you need the 12V SCW for the fans and for powering the on board controller. In a pinch you can power those features using a 12V "walwart" power supply. Just connect it to the +12V terminal and a ground terminal at the power input screw header.That will get you up and running while you wait for the SCW's to arrive.
As for some example code- I'm working on some right now. I suck at coding but I'm doing my best to cobble something together. I've got an DS18B20 and an I2C 20 x 4 LCD working on mine so far.
I find that I rarely ever mess with the lighting schedule over my tanks, so I may just run some control code without a GUI in place for now. Buttons, on screen menus & alike can come later.
 
cool look forward to seeing the code and see if i can help with it :)

The 8 drivers i got from you

What resistor do i need to change if i want to run at 700ma or 1000ma

Thanks again

I was sure you emailed me this but can not find it :(

It's the one marked "Rsense". You'll need a .286ohm for 700ma,a .2ohm for 1000ma OR you can "play in the Big League" and use a .14ohm for 1400ma operation.
 
I've ordered an I2C 2004 screen for mine. Also going to build a manual dimmer using an I2C ADC (8 channel) and some simple slide potentiometers, coloured LEDs to match the channel colour and an external box. Code the arduino so it recognises if the I2C ADC has been plugged in and if so, sets the PWM setting based on whatever the pots are set to, at all other times uses the program timer. Main reason for this is that I'm building a test light first, to work out what mix of bulbs and drive current I need to get a colour mix I'm happy with. Got a selection of XML/XML2 whites, XTE RB, XPE blue, 5W 660nm reds (unbranded) and want something else (UV? Turquoise?). Might run the whites (warm, neutral & cool) on different channels, which means I need at least 6 channels, without taking into account UV, turquoise, multiple channels for the RB and maybe an IR channel for night time feeding :(

Good job I bought 2 boards (altho no idea how to hook them together, but can obviously use them separately) :)

Altho I'm also thinking about using an I2C PWM chip (I already have a PCA9685) so could just drive both boards from that and use only one of the arduinos. Seems like a waste tho. Was going to order some of JoshLawless' designed 6up boards, so might use one of these with the PCA9685 chip controlling PWM to all 11 available channels.

These boards, especially with the jumpers for drive current are fantastic :) I'm guessing swapping jumpers whilst on would be bad? ;)

Uhhhhh- yeah, don't pull the jumper while the driver is in operation. Bad things happen. I learned that lesson the hard way.(Good thing I've still got plenty of A6211 chips)

Let me know when you get your hardware and software sorted out. I'm looking forward to seeing what you come up with. I'm struggling right now to adapt some code that features Geocentric timed lighting periods. The code I'm using has some timing "bugs" affecting my PWM fans & Lcd, causing them to shut down at weird intervals. I'm trying to sort out the problem, but may just have to scrap the idea and go with something simpler. LOL

Just thought I would let you know that today I received my package with my 1500m/A drivers. Thanks a lot. I have just one question My drivers are fitted into a box which sits on top of the LED heat sink. The box is about 150x 100x 65mm. Inside is my driver circuit board which holds 6 LDD's. I am going to swap out 3 of them for the new ones. Do you reckon I should install a 40mm fan into the top of the box to cool the new drivers or can they cope within a closed box with the other Meanwell LDD's?

Duh-oh! I'm glad you asked. Yes, by all means, get some cooling air flow into your driver enclosure- The LDD's will appreciate it too. The drivers I sent you can push around 1600ma on average, so a little air flow really helps them keep cool. Each driver has built in overheating protection and won't suffer any permanent damage if overheated, but no one likes to see their Leds begin blinking on & off when the drivers reach their thermal limit. lol
 
Muhuwahahahahaha!

Wifey's out of town till Monday. Time to start a new led build while she's away! I drug out my 6' makers heat sink today and slid the fans and 5 channel drivers into position, just to see what it will look like. Gonna be a busy day tomorrow. I've got 12 BridgeLux Vero 18's and some other needed bits coming in from DigiKey. This is gonna be fun.....and pretty darn heavy. lol

Check out the 5 channel drivers. They almost appear to have been designed to fit there. Go figure?
