Part Number: PMP10783 Tool/software: Good day Sheng-Yang.
Am designing a buck converter input voltage 80V to 120V and an output voltage of 51V, output current of 0.5A using the PMP10783 reference design. Please advice me on how I can go about powering…

Hello Team,
We are referring the PMP10783 for HV to LV supply design.
Our requirement as follows.
Vin typ = 450V DC
Vout Typ =15 V dc
Iout TYP = 0.8A.

Hi,
I have tested this design ( Rectifier section is not implemented ) and we found following observations.
These are the waveforms for input voltage of 150VDC & 250VDC. ( Rectifier section is not implemented ).

Part Number: PMP10783 Other Parts Discussed in Thread: PMP20708 Hello,
I want to know if I use the same design for low input voltage ( say 30Volts ).?
Since during low input voltage for getting the same output voltage I assume duty cycle of the converter…
Part Number: PMP10783 Good morning, I would use the schematic of PMP10783 board for my project. My fear is born because I can not simulate the circuit with tina. The schematic is reliable and running?
Thank you
Lorenzo
Hi Bipin,
I'm the design engineer for this project. I didn't use TINA to do the circuit simulation. Instead, I simulate the circuit in Simplis. You can download the intro version from Simplis website ( simplistechnologies.com/) to run the simulation…
Hi Ajmal,
The original designer for PMP10783 (Sean, who is helping you on the other thread) is out of the office, so I will try to answer as best I can.
First some general comments 14V/6A with a non-sync approach is going to require a massive heatsink…

Hi All,
The R10 which parallel with Q1's Gate and source thermal, I'm learning its purpose is discharge Cgs during Q1 turn off. Just curious, why it connect with R11 rather than with SW? Any one can explanation? Tks.
Regards…
