Part Number: TLC5960TLC5960 Vadj Pin dimming is 0.12V 10%~1.0V 100% per CH current output 12~100mA
OSD brightness currently sets 0~100 steps , 0~45 steps, 8CH backlight is normal
8CH backlight is normal at 66~100 steps
Backlighting will be Flashing from…
Kazuya-san,
The TLC5960 is also an LED driver. Can you please check the part number again? Also, I generally do not support DAC converters, but I will mention this post to the DAC applications engineers.

Thanks Arief and Anston. I have 3 option of architectures on my hand right now. 1 is as I showed on my previous post, using LMZ235003 as Current Supply. But the price is to expensive to use them on each channel of 32 channels of Load. Btw, in the past…
Hello Hanamanthu,
Please check TLC5960. The part uses external FETs to sink the current and can be used for such high LED string voltage.
Best regards, Brigitte
Hello Han,
Do you need such a high current per LED to just have 1 LED on 1 TLC5970? Generally the part is able to drive 3 LED strings.
If you need such a high current and do not need all the other functions of TLC5970, I wonder if TLC5960 is maybe the…
The huge difference in voltage drops makes this more difficult, as something must dissipate the extra voltage in the lower voltage LED. At 10A, this could be 30W.
It sounds like the TLC5960 LED driver controller could do what you want: http://focus.ti…
Michael,
You might have a look at the TLC5960 (8-channel) driver. It is designed for use with external FETs. It was intended for backlighting applications, but can be used in other high current / multi-channel apps as well. Unlike most of the other TLC…
Other Parts Discussed in Thread: TLC5960 I would like to speak with someone about assisting in the design of a LED driver for a new commercial indoor low/high bay luminaire. We are running high power LEDs and would need dimming capabilities. Could an engineer…
Hello Eric,
Please checkout TLC5960. You need one external transistor per output, but the advantage is you can drive up to 8 LEDs/LED strings with one part, if it is ok that 2 LEDs are turning on at the same time, if not, you can drive 4 LEDs at a time…
