LMZ10500: Programmable output voltage

Prodigy 10 points

Part Number: LMZ10500

I'd like to use LMZ10500 as termination voltage source for a hi-speed signal with Rload = 50. I use I_DAC output to program the LMZ10500 output. Is there any special consideration for the LMZ10500 ?

Thank you very much.

  • Hi Ba,

    It might be worth looking into this application note that uses the TSM84A21 in a dynamically adjustable output voltage application. One thing to look out for is the output voltage slew rate. If it is too high, the converter might high over-current limit and turn the part off. 

    Regards,
