Part Number: LM3481 Tool/software: WEBENCH® Design Tools Hi,
I am trying to design Sepic converter using LM3481 with the below sepicifications. I did simulation in Pspcie tool. Also find the attached diagram of Simulation
Input range - 6V-32V
…
Part Number: LM3481 I have the same question as was previously asked but never answered regarding the reference design transformer part number PA4191NL. Can you supply any generic specs on this part? Inductance? Current ratings?
Part Number: LM3481 Hi Team,
My customer is finding a boost, below are the basic requirements for this:
1. Input voltage: 6~12v
2. Output voltage: 24v
3. Output power: 24W normally, 48W max;
4. Switching frequency around 200kHz for EMI consideration…
Part Number: LM3481 Hello,
I am finalizing my design of a SEPIC supply based on LM3481, and I would like that some TI engineer validate my schematic, please.
Vin = 23.5 to 28V
VUSB = 5V
BATT_LIION_OUT = 3.2 to 4.2V
Iout = 220 mA / 1 A peak …
Part Number: LM3481 Hi,
Please review the attached LM3481 Auxillary power supply design.
I have never worked SEPIC converter before ,so kindly check the schematic and give me review comments as earliest.
Following are my design specifications: …
Part Number: LM3481-Q1 Other Parts Discussed in Thread: LM3481 Hello Guys,
Good day.
Our customer is using the LM3481 Unencrypted PSpice Transient Model in simulating the Load Dump Transients injected to LM3481-q1. The simulation time takes very long…
Part Number: LM3481 Hello,
In the SNVA761A application note , page no.8 , the transfer function of compensation circuit is given.
The mid band gain for above transfer function should be = (Kopto * Rup * (R1+Rfb1)) / (Ropto * Rfb1) . But in page…
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 Hi Team,
Could you help to comments why we add D4 D5 on feedback net of LM3481?
Thanks.

Hi Meng,
The author of the app note has other considerations which are not explicitly expressed. The flyback has right half plane zero pole Frhpz, which is the lowest at min Vin, and you usually place your fc not higher than 3xFrhpz. This example the…
Part Number: LM3481 Other Parts Discussed in Thread: TPS40210 , LM5022 Hi Team,
My customer is using LM3481 in their design. Blow are two questions:
1. The power loss of VCC will increase when Vin goes up. Can we address this issue?
2. LM3841…
