Other Parts Discussed in Thread: PMP Dear TI members,
We have use PMP4626 TI design to our product, but we face a problem about audio noise.
Test condition, input 12V/1.5A and output 12V/150mA(Light load), the condition transformer happen audio noise. …
Here are 2 solutions Robert.
The first one I used Webench, it is always worth a try when looking for power design ideas. The design printout is attached. 12-18Vin, 10.5Vout @ 0.55A isolated. LM5022 controller, flyback, with opto coupler feedback. a very…
Hi Sneha,
This reference design is close to your requirement, www.ti.com/.../PMP4626
Or you could use a flyback power stage controlled by the UCC3800 controller however there is no reference design that is close to your requirement.

If you search TI DEsigns by parameters, you get an interactive page where you can specify your input voltage range, output voltage, output current, AC or AC inputs, isolated or non-isolated, etc. The tool will gradually narrow the number of matches…
Hi Thiago,
It is likely current limit is being triggered. Can you confirm by checking if the SS pin waveform is similar to Figure 26 in the datasheet?
It would be good to compare the layout of your board to the PMP design. PMP7132 was built up on the…
Hi Scott,
If you go to the PowerLAb Ref Design Library page : http://www.ti.com/lsds/ti/analog/powermanagement/reference_design.page , click on Isolated, you'll get a listing of the PMP Reference Design. Click on the Output Voltage column, scroll down…
