Part Number: LM3481-Q1 Other Parts Discussed in Thread: LM3481 Hi Team,
The customer is currently using a SEPIC circuit to charge the supercapacitor, with a 9-16V input and a maximum current of 3A. The frequency waveform of the switching (SW) needs…
Part Number: LM3481-Q1 Tool/software: Hi,
I want to use this LM3481-Q1 IC as a pre boost solution, but I am able to understand the functioning of the pin FA/SYNC/SD.
In my application, I want to use both the FA & SYNC functionality.
can I use both…
Part Number: LM3481-Q1 Tool/software: In my application, input is 5V to 18V, my output is 11.64V, my duty cycle when Vin>8V is 34% & below, so Ton time =below 377ns when switching frequency is 917KHz, so what is the behavior of the output when it is below…
Part Number: LM3481-Q1 Tool/software: Dears:
Customer want to use LM3481-Q1 to drive three transformers in parallel to cost down.
below is the simplified picture.
Could you please help advise if this solution can work well ? Any design guide is…
Part Number: LM3481-Q1 Tool/software: Hello, I am using a excel 2011 (french) and when it try to open and use LM5185-DESIGN-CALC.XLS, i got the following error when openning it:
It translate to : "There was an error in the content of the LM5185-DESIGN…
Part Number: LM3481-Q1 Other Parts Discussed in Thread: LM3481 Tool/software: Hi TI team,
My customer is reviewing the module for emergency power supply of SBW.

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…
