LM3478: lm3478

Hi Hubert,

Unfortunately, I cannot find a reference design with the LM3478 that meets your exact specifications.

However, I've attached is a LM3478 reference design that generates 200V @ 0.01A http://www.ti.com/lit/df/tidre38/tidre38.pdf?ts=1590514901543 that utilizes a boost converter followed by a charge pump. Unfortunately, a charge pump will make your output current much smaller than what you would need. Additionally, if you use a single-stage boost converter your duty cycle is quite high, and as such this will limit your switching frequency and selection of available controllers. 

There is another reference design that follows a similar concept and utilizes LM3481 http://www.ti.com/tool/PMP20183. 

You may try cascading different stages with different controllers to see if you can generate your desired output, but there seems to be no available reference design for this. 

Thanks,

Richard
