Hi Shinichi,
Thanks for using the e2e forum.
LM3478 and LM3488 can indeed achieve high boost rating due to 100% max duty cycle, however, I could not find any reference designs for a 300V/30W output.
I see no restrictions for these specs within the datasheet…

Hello,
I have found your design for LM3478 http://www.ti.com/tool/PMP10077 .
I had downloaded CAD design files " PMP10077 CAD Files " and opened it with Altium Designer (viewer license). But it seems that the…
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: LM3478 Other Parts Discussed in Thread: LM3481 , PMP10077 Hi,
My customer is asking on using LM3478 to achieve 3.3V Vin to 120~200Vout, 46mA Ioutmax.
a. can this be achieved using boost topology?
b. if #a is not, can this be achieved using…
Hi Kevin,
Attached is a reference design using the LM3478:

You can use the reference design using the LM3478 as a start for your…
Part Number: LM3478 Other Parts Discussed in Thread: PMP10077 Hi
Our customer wants the IC that meeting following requirement.
VIN:10.8V - 26.4V
VOUT:150V-200V
Iout : 10mA
We are referring the reference design of PMP10077 because it seems to be close…
Hi Kevin,
If you would like to use the LM3488, please take a look at this reference design: www.ti.com/.../PMP10077 as a starting point for your design.
The design using the LM3481 is also helpful:

If you would like to control…
Hello Louis,
Please take a look at PMP10077 . This is a high voltage non-isolated boost converter designed with the LM3478. The LM3478 is very close to the LM3488.
If you need an isolated solution please follow this design guide aid in creating a flyback…
I looked at the LM3478 for a VIN = 3V, VOUT = 150V, 20mA design, but Webench will not generate a working design. PMP10077 is close with VIN = 20V, VOUT = 200V, so I'm wondering if it can be modified for these requirements? www.ti.com/tool/PMP1007…
Hello John,
Our customer want to genarate 200V/20mA power supply from 15V input with any TI power IC.
I proposed the customer to use LM3478 for the power supply with flyback topology.
But the customer didn't agree to use the device because the solution…
