Hi all !!
I'm designing an Aluminium PCB for driving high power leds, RGB 3x3W each 9 leds in board. The question is:
What about pchip working on a power sink at temperature of about 50 degrees ??
Do you think that will work without any problems, xtal, eeprom, pchip, SN75176, LDO regulators. etc ??

Thank you so much for your opinions.
Best regards for all comunity !!

    Is that 50 degrees C or F?

    The data sheet (table 7.2) lists the operating temperature range of -55C to +125C so you should be okay -- so long as you're not trying to light the inside of an oven! :)

    Is this a DMX fixture?

    Thank you Jim and JonnyMac !
    @Jim Yes, I'm talking about 50 C deg.
    @Jonny Yes the design include DMX control, channel select by the eight red leds in board, and usefull pre programmed effects mode, for pool lighting users.

    Regards !!
