Part Number: LM51561-Q1 Tool/software: Dear team,
During the application of TI LM51561-Q1 in SPEIC circuits, overcurrent damage may occur in D400 (using VSS8D3M15HM3-H, If3A, Ifsm60A) when powered on (different power supply models may have different…
Part Number: LM51561-Q1 Hello! On my last post ( https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1521807/lm5156-q1-sepic-converter---mosfet-overheating/5850758 ) I shared an issue I had with a SEPIC topology…
Part Number: LM51561-Q1 Tool/software: Hi Team,
I hope this message finds you well.
I am currently seeking a detailed 3D model that includes internal components such as the die, bond wires, and lead frame. While I have downloaded a STEP model, it…
Part Number: LM51561-Q1 Tool/software: Good day, colleagues,
To activate the dithering, the pin shall be connected to GND. In the Datasheed I have seen, that the device has schmidt trigger for the activation and deactivation: The question is: How great…
Part Number: LM51561-Q1 Other Parts Discussed in Thread: LM5156 Tool/software: Hello,
I've noticed an issue with the LM51561-Q1 PSpice model available on the IC details page. The model assigns the global node 0 to the ground pin, but it should be connected…

I'm trying to simulate flyback circuit with LM5156 controller with LTspice. Would it be possible to get unencrypted spice model?
I also have tried to use…
Part Number: LM51561 TI WEBENCH - LM51561-Q1- Flyback
Hello Team,
I wanted to design a flyback converter with Vin of 10-18V and Vout of 12V with Iout as 3A.
I used quick start calculator and tried to design using TI WEBENCH with LM51561-Q1 Flyback…
Part Number: LM51561-Q1 Other Parts Discussed in Thread: LM5156 , LM51561 Hi,
I am designing a flyback converter 75W with a hiccup function for mass production.
The hiccup happens continuously, but the current limit is not reached(verified transformer…
Part Number: LM51561-Q1 Other Parts Discussed in Thread: PMP31279 我参考的是官方的PMP31279的设计，其输入输出参数为 VIN 6-12V ,VOUT = 12V, IOUT = 1A.现在我将其参数原封不动的不变，实际测得最低启动电压，确实是6V，现在我想使启动电压的更低，因此，我将其第12脚（UVLO_SYNC）直接上拉至VIN，然后将从VIN连接到BIAS脚的二极管，更换为压降更低的肖特基二极管，实测下来最低启动电压，能够达到4…
