Part Number: LM3481-Q1 Hello,
We have a SEPIC design including the LM3481-Q1 controller.
According to the datasheet, Cin should be above 100uF.
However, the Powerbench suggests Cin to be tantalum 4.7uF.
The questions are:
1) Who should I follow, the datasheet…
Part Number: LM3481 Hi team So i've been using the LM3481 for a sepic converter for a while and i have had problems with the board (Please refer to the previous thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management…
Part Number: LM3481-Q1 Hi team,
I'm BCCing this thread to my customer. Could you tell me if you can provide the password for this calculator--FLYBUCK-FLYBACK-DESIGN-CALC? This is because they'd like to see how the result comes out. Specifically speaking…
Part Number: LM3481 Other Parts Discussed in Thread: TL431 , Traditionally flyback converters are designed to obtain fixed output voltages at variable input voltage ranges with galvanic isolation and literature is available widely for such designs.

Hi
We found that there are indentations on the back of this product. Could you please confirm the cause of this, or the process problem, and whether it will affect the use
Thank you
Part Number: LM3481 Other Parts Discussed in Thread: LM5155 Hi team,
I’m trying to get bode plot using LM3481 average model in PSpice for TI, as referring to this E2E . I’m planning to have DAC-programmable output in the range of 2.5V~15V in SEPIC…
Part Number: LM3481 Hi team,
I’m trying to design output-programmable SEPIC with LM3481, and facing a challenge. Would you please take a look, and provide suggestion?
The basic requirements are,
Vin=5V
Vout=2.5V~15V
Iout=0.8A
I add adjustable…
So adding a heatsink or going for a board with better planes and 2 ounce should help with this right?
Brigitte said: I expect that the MOSFET temperature is almost linearly rising with load
Actually up until a 0.5A load this is true and the mosfet does…

Hi everyone:
I have a question about LM3481-Q1 ULVO pin Maximum Voltage, in datasheet, the maximum value is 6V. But in “AN-2094 LM3481 SEPIC Evaluation Board”, when Vin = 25V, the…
