Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: PMP22343 Tool/software: Hi.
I have built a +/- 30V PSU following suggested PMP22343 design following the specs rules however I get a very noisy output but what is worst the waveform is oscillating in a sort of manner.
Here attached the schematic…
Hii John Dorosa
VR3 is not present in the tested circuit from the start and only parallel resistor across VR3 is connected of 1K ohms value. D2 is zener diode of same part number which has been used by TI 43 V rating,... D1 and D3 are Schottky diodes…
Part Number: PMP22343 Following PMP22343 design I have built a board for 12V to +/-30V conversion. During testing when i am powering up the circuit through a Keysight bench lab power supply DC at 12V with a 1,5A max CC current limitation it is immediately…

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