Hi Diego,
Thank you for using E2E forums, For your query I think LM5155/56 could be a good fit, you can check the device and it's quickstart calculator here ti.com/product/LM5156.
Furthermore, you can also check for reference designs with your design…
Hi Phil,
Currently, the most suitable IC that can suit your application is the LM5123. However, you can use other boost controllers, such as the LM515x controller family. You can follow the adjustment voltage scheme shown in PMP20212: https://www.ti.com…
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…
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.

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…
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.
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,
Youhao
Hi Chentsu,
The LM3481 is a good solution for this application.
Here are two example design using the LM3481 in a boost configuration with a voltage doubler on the output. These designs are a good starting point.

Hello Polly,
You may refer to www.ti.com/.../PMP20212 in which a LM3481 boost with a couple of charge pump stage can produce a high output voltage. The LM3478 seems able to do this in a single stage boost, but it should be in DCM to avoid requiring…
