Part Number: LM51561-Q1 Other Parts Discussed in Thread: LM5156 , LM51561 Tool/software: Hi,
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 tina…
Part Number: LM51561-Q1 Other Parts Discussed in Thread: LM5156 Tool/software: Hi,
I want to design a boost converter to have a 160V/50W output, max 80W. The input voltage is between 9-30V so I did a flyback design with the LM5156. I attached the SNVC240…
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 current…
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…
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: TPS40210 , LM5155 Hello together,
currently, I'm working on a new DCDC converter. For that, I would like to do some simulations in MATLAB Simulink. Therefore I would like to ask, if a working model…
Part Number: LM51561-Q1 Other Parts Discussed in Thread: LM5156 Hi,
I have tried importing the unencrypted SPICE model in the LM5156 product folder into LTSpice and it is giving error. When I looked at other posts in this forum there was one with a similar…
Part Number: LM51561-Q1 Hello,
We would like to share with you a new issue due to a bad performance of the chip during a test at 65ºC and 90% humidity. After a visual inspection with the microscope we observed some of mould or whiskers on the exposed copper…
Part Number: LM51561-Q1 Dear team,
When the FB pin voltage is smaller than Uuvth, PGOOD will go low. If PGOOD is low, how does the output change? Will the output be turned off?
Thanks & Best Regards,
