I designed an inverted power supply with input voltage of 24V and output voltage of -15V using TPS54260. I used the calculator as well as reference designs from the TI website. But unfortunately the power supply is producing around -7 volts instead of -15V. I am attaching my design as well.
I tried to change the Cin as well but of no use.
Any help in this regard is highly appreciated.
Thanks and regards;
I don't see anything obvious. Can you post some waveforms? Vin, Vout, PH? What is your load? Can you test it with nothing attached? Or possibly 30 ohm?

how did you solve your problem?
