Part Number: LM51551-Q1 Tool/software: hello
i checked the LM51551-Q1 DATASHHET ,the following PICTURE
As we can see from the following figure, when VCC exceeds 4.5V, the voltage of SS pin starts to rise,but refer to the Red Arrow Position,
When SS rises…
Part Number: LM51551 Tool/software: Hi TI team,
Please share the procedure to calculate the theoretical efficiency of LM51551 as flyback converter. Please share if any documentation available.
Part Number: LM51551-Q1 Tool/software: Hello,
I have made a power supply using LM51551-Q1 with Flyback configuration. I am simulating the circuit in TINA TI. The issue is IC is not producing any output. Don't know whether its a TINA TI simulator issue…

Part Number: LM51551-Q1 Tool/software: Hi team,
My customer is considering to use LM51551-Q1 in flyback DCM mode. But I cannot find the calculation tool for DCM mode.
Could you help check and provide the guidelines for calculation in LM51551-Q1 DCM mode…
HI Moritz,
Moritz said: Just to clarify, everything works normal with the other diode?
using Schottky can normally operate but if not Schottky, the 54Vout would be unstable and very hot at full load.
Moritz said: I would recommend to place a snubber across…
Part Number: LM51551-Q1 Tool/software: Dear Engineers,
I want to use this reference design (PMP40488 ) for one of my application.
I noticed if I used coupled inductor for L3 and L4 I will get better performance and the value of the positive rail and…
