Part Number: LM3481-Q1 Hi Team,
Based on LM34xx How to Design Flyback Converter with LM3481 Boost Controller (Rev. A) (ti.com.cn) , my calculation of Lm is about 110uH as below.
VIN=32V Vout=12V. others are same as below.
However, in chapter 4, it says…
Part Number: LM3481 We want to the following Specifications:
Vin = 12V
Vout = 24V, 2A
V Output Control with PIO pins.
The circuit diagram we currently use is as follows.
PIO Control L(0V) = Vout 12V
PIO Control H(3.3V) = Vout 24V
We want the output…
Part Number: LM3481-Q1 Hi team,
This is Chloe, NWC AA2 FAE. There is an issue about small signal model derived. Such as Figure 6, write the KCL equation according to the last sequence of small signal circuits, and compare formula 14 to get the relationship…
Part Number: LM3481 Other Parts Discussed in Thread: LM5155 Hi,
Does LM3481 possible to using for below LED design? Seems it can't fix output current?

Part Number: LM3481 Hi team. I've been working on the LM3481 SEPIC converter for a while now and it alwyas keeps on comin up with newer problems. Vin:18V to 30V Vout:24V/1A A coupled inductor design is being used and the DRQ125-220-R is being used as…
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 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-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.
There…
