The question about parallel output of TLC5940

Taichi Noda

Other Parts Discussed in Thread: TLC5940, TLC5922

I am being asked a question that whether TLC5940 can output over 120mA current by customer now.
For example,in the case of driving 240mA by 2ch.

I checked some datasheets and applicationnotes,
I found an applicationnote"LED Driver--Paralleled Outputs Provide High Current Outputs" on
http://www.tij.co.jp/product/jp/tlc5940.
It is writed that TLC5922/23/24 can take output parellel but,
never writed that TLC5940 can take a parellel output.

Please tell me whether TLC5940 can take a parallel output.

Best regards.

Hello Taichi,

Multiple outputs of the device can be configured in parallel to increase the constant-current capability.

Best regards,
