Part Number: PMP20212 Other Parts Discussed in Thread: LM5156H , LM3481 , , LM5156 Tool/software: Hi team,
I would like to make the exact same reference design as the PMP20212, however using the LM5156H instead of LM3481.
Will this be possible?…
Other Parts Discussed in Thread: PMP20212 , PMP30722 , POWERSTAGE-DESIGNER Hello,
I am looking for a non-isolated boost controller to boost +24V +/- 5% up to a variable Vout of +26.5 to +32.5V with Iout of 8A at +32.5V. I need to drive the adjustment…
Hi Ashwani,
Do you need isolation for the application? If not take a look at PMP20212.

This concept of stacking a charge pump on the output of the boost converter is good for high step up ratio designs, similar to this application…
You need a boost controller with external FET. There is a 300V out ref design. You do not need the multi level charge pump and the just single boost stage of that design should support your application.

Two options: one is to use a flyback with high secondary to primary turns ratio to produce the high output voltage, The other is to use a boost in multi stage charge pump configurations. There is a refer design for the later option: www.ti.com/.../PM…
Hi,
A combination of a boost stage and charge pump stage should work. Please refer to the following designs in this link:
www.ti.com/.../PMP20212 . This should be a good starting point.
I see PMP20212 is "close" but would certainly need some work for extra V and I: http://www.ti.com/tool/PMP20212 .

Hi Ilya,
Actually we have a ref design to produce 300V from a low voltage source, just using a different device the LM3481. You can find the info at the following link:

Thanks,

Hi Liven,
What are your input voltage range, and output current requirements?
There is a reference design that utilizes a boost power stage to generate high voltages (150V - 300V) @ 10uA that could be suitable to your needs.
