Part Number: PMP20127 Hi,
We had made Same to same Eval Board reference Design for testing before size reduction of PCB for our use.
Input -12V DC from 12v/3Amp SMPS (Design Range 9-125V)
Output-5V DC
Load -0.5 -3Amp
Fault-Audible Noise
Output Noise Level…
Part Number: PMP20127 Hey,
we used your PMP20127 with some modifications in schematics and PCB. But we getting noise pk-pk upto 1.5V in output at 1.6Amps load and board is also have heating issue. just guide me to resolve this.
Schematics is attached…
Antonio,
Thanks for connecting through E2E. As a starting point, you can search the TI reference design library here . I was able to find PMP20127 and PMP20196 which are both wide input flyback converters close to meeting the requirements you posted. You…
Hello Jean,
A search through our Reference Designs indicates that the LM5022 is used quite often for such a wide-range type of application. Although this part is originally targeted for boost and SEPIC applications, it is also widely used for isolated…
Hi Gerrit,
Thanks for your interest in UCC2897A. The recommended max voltage of the VIN pin on UCC2897A is 110V with an absolute maximum rating of 120V. If you can clamp Vin externally, yes you can use this device for your application.
You could do…
Hi Fran,
You could try boosting 3V to 6VDC Vin to 9V Vout at 2.5A using a TPS61088 and OR it with an ORing diode with the LM5022 Reference design in the PMP20127 as Sonal mentioned.
The TPS61088 will operate under low VIn conditions and LM5022 will…
Part Number: LM5022 Other Parts Discussed in Thread: PMP20676 , PMP20468 , PMP20127 My customer has a Flyback design based on the LM5022 and is concerned about the oscillation he sees on the SW node after the controller turns off the primary side power…
