Other Parts Discussed in Thread: UC1825

How to Configure UC1825 so as to use only to generate PWM by comparing with RAMP for following external voltage and current error amplifier having +15V and -15V supply?

How to configure UC1825 if I want to use external voltage error amplifier instead of internal error amplifier?

Kamlesh,

Is your configuration a single output or are you trying to parallel multiple outputs.
What is your topology / configuration?
You should be able to put the internal op-amp in unity feedback and then use an external op-amp with compensation to close the loop.
