Forum Post: TLC5923 and multiple LEDs Vcc

$

 I have a question about the TLC5923. In the TLC5923 datasheet, page 9, figure 9, you can see the LEDs anode connected to VLED. They are all connected to this power rail, VLED. I have the need to connect some LEDs to VLED1 (5V), and other LEDs to VLED2 (12V). In both case, the current limiting is the same, 20mA.

Can I do that, or VLED _must_ be the same for all LEDs?

Thank you!
