How to increase PL voltage level of Bank-34 and 35 on carrier beyond 3.3V?

Question

I want to voltage/current amplify all 100 digital outputs of bank 34 and 35 in the input/output carrier card beyond +3.3V for e.g. upto +7V instead?. The application I'm working on requires me to drive output loads each of which are 1kohm ideally at 50mW using the Microzed PL outputs. I have a Microzed with zynq 7010 with i/o carrier board connected to it. Are any board level interventions (adding or changing any voltage regulators) possible for my application ? Or are there any other ways of approaching this requirement ? ( I read that the microheaders can support upto 500mA per pin). Thanks

Hi Nagarjun,

That's not possible. If you really need 7V output then that requires extra hardware to be attached (for example a BJT or MOSFET, or logic buffer ICs - designed to cope with your end requirements, along with a power supply to drive your additional extra hardware).
