Part Number: PMP9087 Dear TI Team,
With due respect, I am an electronics engineer and like the TI reference kits. I want the Schematic file (.Sch) that can open in the altium software of the given part number PMP 9087. It will be helpful for me in the…
Part Number: PMP9087 Hi team,
Could you give me comment on following customer question?
Q1. How can I calculate R4 and R5 value on PMP9087 for following current requirement?
For the customer's design, average current: 300mA, peak current: 2A.
Best…
Part Number: UCC28710 Other Parts Discussed in Thread: TINA-TI Dear Team,
I am trying to simulate the reference design PMP9087 with TINA-TI but the results are wrong. It seems like the UCC28710 spice model does not start up properly and thus the output…
Part Number: PMP9087 Hello,
we are interest in design an high voltage to low voltage non isolated buck converter. We found the PMP9087 reference design that meets our requirements but on the ucc28730 there are no design equation for buck mode of usage …
Part Number: PMP9087 Hello,
I am planning to modify the PMP9087 design for an input voltage 110Vdc - 200Vdc to 5V output and output current of 500mA. Need clarification on the design modification required other than feedback resistors.
Also want to understand…
Hi Anand,
PMP9087 design meets your specification.
I also upload my design flow and calculation of designing a buck converter using PSR Flyback (UCC2871x).

Hello Mike O',
After reading the document, I have monitored the VDD and observed that the VDD is a triangular wave with Vdd0n =~21V and Vddoff =~8V as expected for undervoltage. In the current circuit, I have three 10k resistor on the HV pin which…
Hi,
I think you might have to build one for yourself from the available schematics. It is not available to order.
Few other references designs:

Thank you
Dear Jaehwan,
Thanks for interested in TI's solution.
In TI's portfolio, flyback controller with built in MOSFET didn't support high power.
What is the output power, voltage, current in your design?
You can also provide more spec detail,…
