Other Parts Discussed in Thread: TLC5945 Hello,
I'm interresting by the TLC5945 for a new design.
I want to supply 7 LED in series, so 7 * Vf = 7 * 3.2V = 22.4V, that's why I need to use a LED power supply voltage of 24VDC.
I read in the datasheet…
Hello Vini,
Is this repetitive and the output is just turned on once when you are sending 2 BLANK pulses? Show both cases above exact the same behavior? Would it be possible to get zoomed in measurements of the above signals while working properly…
Hello Picca-san,
It's no problem for driveability of TLC5951 between IC to IC if SCK can keep a timing on data sheet.
But SCK timing is depend on controller driveability , PCB layout or line capacitor on PCB board whether it need buffer or not for…
Part Number: TLC5954 Other Parts Discussed in Thread: TLC5945 , TLC69601 , LP5860 Hello,
What bit-depth is the TLC5954 capable of? I.e. how many colors is it capable of displaying, per LED?
If the bit-depth of the TLC5954 is not at least 24-bit…
Hi, David,
Sorry but I failed to unlock that thread.
If you want to disable LOD you can try TLC5945 or TLC59461.
These are PIN compatible devices and won't turn LED off even LOD is detected.
Thanks.

Kenneth
Hello Kenneth,
After long time we made test in thermal chamber within current up to 70ma. It seemed that thermal event did not appear. I think that is appropriate layout with a lot of polygon and heatspreader. After counting power dissipation everything…

Hello Chuck,
Let me try to answer your questions:
1. Calculation is almost correct, just some time for XLAT and BLANK has to be there, which increases the data transfer speed.
2. The e xtra clock is just needed once after all bits are clocked…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
