Part Number: PMP8621 Hi Sir,
My customer want to design a 5V to 180Vdc / 0.01mA circuit. They find PMP8621 and want to know if that's ok for 5V input application, and what's the output voltage when its Vin = 5V? Thanks for your kindly response.…
Part Number: PMP8621 Tool/software: TINA-TI or Spice Models Hi Community,
I was trying to simulate the reference design PMP8621 in Tina-TI.
However I could not get the expected 300V output and there was no output at the GDRV pin of the TPS40210 model…
Hi Angel,
Thanks for the feedback. If a flyback topology is not possible due to transformer size, two boost stages with a LM5155 and another controller might achieve smaller solution size. There are also alternative topologies, which achieve higher boosting…
Hi Mike,
There are a few TINA simulations for the TPS40210 . Scroll down to the TINA Startup Reference Design shown below.
I think I would start with the Startup Reference design and re-configure it for the PMP8621 design.
First, I would run the Startup…
Hello Hirano-san,
Thanks for your reply. This type of configuration boost + charge pump is also possible with the TPS40210, at this link you can find a similar reference design https://www.ti.com/tool/PMP8621
Let me know if further assistance is needed…
Hello,
Thank you for the feedback. As you plan to have a pretty low input voltage, I would suggest to use the approach with the charge pump, like in figure 10-8 . At this link you can find a reference design with a similar device to the LM51551 ( https…
Hi Darren,
Thank you for reaching out but the LM5156EVM alone does not seem to be a good start point. You may refer to the following ref designs and "transplant" the power circuit to the LM5156. You need to change the current sense resistor because…
Hi Zhonghui,
I advise to take a look at the following reference designs and see if they can help.
https://www.ti.com/tool/PMP10077 - This reference design uses LM3478EVM, but the base level design should be the same. You will need to change the feedback…
Part Number: TPS40210-HT Dear colleague,
Now our customer want to use TPS40210-HT design a power.
Vin=5-33V, Vout = 1300V, Iout=0.5mA
And customer study the PMP8621, but this design don't show the design process.
So could we provide the PMP8621 design…
Hi Darren,
Thank you for reaching out and considering our products. I would like to recommend the LM5155, our latest boost/flyback controller superior to the LM3478.
Anyway, both LM5155 and the LM3478 can support your applications.
For such high step…
