Part Number: LM3481 Other Parts Discussed in Thread: PMP10098 HI
I have a wide input design requirement, want to reference as PMP10098 DEMO board,
I have a question about power start-up, attach file is SCH
If input=19V，Q3 could not work, How the…
Add: The list shown in Figure 6 reads the reference circuit of the KCL equation as follow:
And the application report SNVA761A is attached. snva761a.pdf
Hi Pieter,
Thank you for reaching out. Webench put a 300V limit due to its library components limitations. Theoretically there is no max Vout limit except the boost duty cycle limit.
There are several 300Vout ref designs, which was also mentioned…
Part Number: LM3481 Hi Ti Support
Same as Paul,
i'm looking for transformer spec designed on TI ref design http://www.ti.com/tool/PMP20981 .
based on the BOM, part# PA4191NL (Pulse Engineering) => not found on the web nor Pulse website
I have…
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…
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:

Specification:
Vin : 13 to 14.5vdc
Vout : 16.5v
Iout 4A
Fsw : 300Khz
Issues faced…

Part Number: LM3481 Hi Sir,
I've saw the datasheet of LM3481. I have a question about the peak current control.
The diagram shows that the peak current control signal comes from the output of EA which compares FB voltage and 1.275V ref.
But in…
The Ref Design is a DCM circuit and the duty cycle should be adequate to support 5V in. You may consider to reduce the current sense resistor if it hits the peak current limit of the LM3481.
