AMC7135 LED DRIVER DOWNLOAD

So I could be very wrong on this. I have this documented in various lights at various total output figures. See “exponential decay” or “radioactive decay”. It partly depends on the programming of the driver. Would a second board running only chips and in slave mode be a better option than stacking? Please look at the chart I posted above, and pay attention to what it means. There is nothing in the datasheet to hint that the current sink can switch in kHz range usually required in lighting control.

Amc7315 light I saw at has different configs available and those I mentioned above has 2 groups and can be switched to 3 modes or les modes. Leave a Reply Cancel reply Your email address will not be published. The time required by the current sink to become stable is about 8us. That is not a good way to drive the AMC as the brightness will suddenly decrease in the lower ranges of duty cycle.

But this should be sufficient to get the point across. As in this screenshot, the duty cycle is at its minimum possible here.

When I take a Qlite up to 6A output, Lo is not a percentage of that new 6A figure, but instead remains the same or very close to it as the original 3A board. Each one allows mA. According to the graph posted by ChiggerPepi:. I have this documented in various lights at various total output figures. Log in or register to post comments.

This can be seen here:. Here is the test circuit I used to check how long it takes for the circuit to draw a stable mA through the LED: And the c board doesn’t even have a complete trace under the middle of the s, just a little pad connected to nothing for the pin and a amd7135 pad in the back for the tab.

Three Tanna leaves to give him life, nine to give him movement. Sorry to dig up an old thread. I had though the modes might be affected by the chips.

To see how this relates to brightness, you can lde by using this graph: This can be seen here: That is, Turn-on time: Starts off very high constant e0 and then decreases more and more rapidly with drive current until it approaches but never reaches zero lumens per watt.

AMC chips are current limiters. So I aamc7135 be very wrong on this. Your email address will not be published. Skip to main content.

It supplies mA per chip as long as the input and output voltage is within the specified range. However, assuming that amc713 AMC is a feedback based current control system, you must consider the time that the device takes to settle to a stable constant current output.

But keeping all the things modest… I think this is the right frequency.

Apologies for my terrible drawing skills! Is that because of losses in the additional amd7135 At about 2kHz PWM frequency, things seem okay! Many based drivers use pulse width modulation to control the lower modes.
