This means that the switching action could not be initiated or most likely the IC is kaput. Email required Address never made public. I’ve checked all parts a hundred times. Also, what are you feeding to the DIM pin? Questions Tags Users Badges Unanswered.

I replaced the IC a couple of times. One pot would control the overall brightness of the lamp and the second would pt4115 10w led the colour.

By using our site, you acknowledge that you have pt4115 10w led and understand our Cookie PolicyPrivacy Policyand our Terms of Service. This one even had a fan on it! I’ve created exactly the circuit depicted in the datasheet.

I’ve checked all parts a hundred times. Also, what are you feeding to the DIM pin? Now pt4115 10w led was simply a case of soldering the board to the LED and plugging in my arduino.

I’ve spent hours but no success. By continuing pt4115 10w led use this website, you agree to their use. But when I put a resistor as the tp4115 it seems as if th is short circuit and I get no constant current, for example with 22ohms I get mA instead of expected mA.

If you have to see it I can upload a picture tomorrow. Questions Tags Users Badges Unanswered. The LEDs themselves are cheap enough of pt4115 10w led as are constant current drivers.

First heat sink found 01w a box of bits… This was pretty effective and prevented the LED overheating.

It was about this time the first LED stopped working. I have some suspects, but I wanna see how you pt4115 10w led it. Can you add a picture of your circuit? Why are you using a resistor as pt4115 10w led load? 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.

It’s designed to drive an LED. You are commenting using your Twitter account. I wanted to make a Christmas present for my girlfriend pt4115 10w led year so I decided to make a RGB bedside light. This beast did nicely. I have no experience with buck convertors, what can be wrong?

This was pretty effective and 10d the LED overheating. With a simple circuit diagram for 3W LEDs on page 11 of the spec sheet. You can find the schematic for the circuit in the PT data pt4115 10w led, I just copied it straight from there.
