Thank you for the additional information. It sounds like something may be damaged or placed incorrectly. Can you measure the input with an ohm-meter? There should be some impedance but from the sounds of it there could be an unexpected short.

Hi Ive simulated the same in Pspice but the simulation results are not perfect. Could you kindly verify the same and revert back.

Part Number: PMP22343 Hi,
I have buit a design using PMP22343 for 5V to +/-40V. But when i am powering up the circuit through external DC source at 5V it going to CC limit without any loading. Kindly help me the same
Hi Lukas,
PMP22343 shows another option for regulation. In this design the differential voltage is regulated, then a Zener diode is added to ensure the negative output does not fly down too far. With that wide of an input you will most likely need some…
Part Number: PMP10733 Other Parts Discussed in Thread: LM5160 , TPS54560 , PMP22343 Hi team,
I would like to adopt this design; however, some components are seems to be a little old.
Especially, the coupling inductor, TA7848-AE, is very difficult to find…
Hi,
thanks you for using the E2E forum.
Maybe this would be a good starting point:
