Part Number: PMP10350
Dear TI Engineer,
As a college student, I ran into this puzzling problem with the PMP10350 reference design. As shown in the schematic of reference design PMP10350, Why is the HV pin of UCC28710D connected to the drain of the MOS…
Viktorija,
We need to see some waveforms from the customer board to see what's happening.
We need to see:
VDD
DRV
CS
Vout
We need to see them on a slow time scale (~1 s/div), and zoomed in to the first several switching cycle (~10 us/div).
Is…

Part Number: PMP9208 Other Parts Discussed in Thread: PMP10350 Good morning!
I would like to know what the modifications in the schematic of the PMP9208 project would be to obtain 12V at the output, maintaining the same power (which would give approximately…
Kuan,
Thanks for the interest here. Are you saying the customer wants fewer external components? or is smaller size most important here?
You may consider looking at controllers with integrated HV startup focused on low system cost. These devices include…
This reference design is close to what you are looking for, Joshi. www.ti.com/.../PMP10350 85-265VACin to 12V 5A isolated output. 60W You are asking for 14V 5A, 70W, so this is close. UCC28710 is the controller. There is a UCC24630EVM, and LM5023 controller…
