I need to do some PWM control of a pump for variable speed control and the voltage level needs to reach 5 volts not 3.3. I did some PWM test on the UC5550 and FEZ and the max is 3.3 volts. I recall seeing that the FEZ outputs are 5V tolerant. Is there any quick way to get a 5 volt PWM with the FEZ? For a regular digital output on the FEZ how would I get 5 volts? The IORef pin reads 3.3 volts.
Long term, I will be using the UC5550, not FEZ. What external circuity would be recommended to get from 3.3 to 5 on PWM for an industrial application? I will be in the 1 kHz to 1.5 KHz range. Thanks!
