  Part Number: UC1708-SP Hi Team, I have a different question on the UC1708-SP. If I’m only using one of the two outputs, what is your recommendation for the INPUT and OUTPUT pins of the unused channel for lowest power consumption? Thanks! Connor

  Ramesh Khanna

  Hi Kamlesh, If you disconnect UC1708 and 5K resistor , are you still seeing pulses out of UC1524 at zero duty cycle. Zero duty cycle implies there are no output pulses. Zero duty cycle relates to where the E/A output crosses the ramp. As this is…
