In fact the first microcontroller I ever bought. Leave a Reply Cancel reply Enter your comment here It also has a power regulator so I can take power directly from the 12V supply.

If you see a short then we can say that the IC is broken. Now it was simply a case of soldering the pt4115 10w led to the LED and plugging in my arduino.

It’s designed to drive an LED. You are commenting using your WordPress. I used an Adafruit Trinket I had spare.

pr4115 You are commenting using pt4115 10w led Twitter account. Fortunately it has just the right number of pins, two analogue inputs and three Pt4115 10w led.

It was about this time the first LED stopped working. The second lower slot is a vent to allow air to circulate from the bottom, up through the heat sink and out the top slots. Post as a guest Name.

First heat sink found in a box of bits… This was pretty effective and prevented the LED overheating. Can you add a picture of your circuit? I’ve checked all pt4115 10w led a hundred times.

If you have to see it I can upload a picture tomorrow. I’ve created exactly the circuit depicted in the datasheet. I’ve spent hours but no success. The LEDs pt4115 10w led are cheap enough of eBay as are constant current drivers.

This means that the switching action could not be initiated or most likely the IC is kaput. You are commenting using your Facebook account. Sign up using Facebook.

I have no experience with buck convertors, what can be wrong? It pt4115 10w led really effectively.

White LED Driver Based on PT4115

Why are you using a resistor as the load? So a good project to get rid of it in. I have used 0.
