Hi all,
I am designing a programmable inverting smps.
the output of the smps will vary between o to -10V.
i chose this circuit (two OPAMP and DAC and Vref for varying my output)
but if i use this circuit, it is necessary to have negative supply for the second OPAMP.
Is it possible to return this programmable circuit without a negative supply ?
Thank you
Paul
