not quite sure what you're asking. if yo want 5v regulated power you already have it. if you want a voltage proportionate to the pwm frequency that's another matter. if you want to output a rectangular waveform with an amplitude of 5v and 90% duty cycle, there are chips that sit on the i2c or spi busses that can do that, the pru can likely do that for you easily, or as slow as it is yo can likely do it in software bit banging a gpio with relitive accuracy. what is it you want to do?
