#109781 - plating purpose Responding to: ???'s previous message |
Andy Neil said:
Don't you mean 30mA ripple? If it's a constant current source, the output voltage will vary however much is required to keep the current constant - so a voltage ripple spec is pointless?? I got it from a person known to me. It's been built and running. Since i couldn't understand few issues with it i have bought it here, just to analyse what sort of output it gives, that makes it a constant current source. Kindly help me know for the good and bad issues with it and also for suitable changes if any. I ask this because when i went through the data sheet of LM 338 i could find the regulator designed in a simpler way, compared to the one i have posted here. Details: The circuit is designed for plating purpose, for which the ripple voltage must be less then 30mV. So that plating is not grainy. The plating time can be varied using a timer that cuts the i/p of regulator when set time elapses. suggestions please. -suresh. I |
