Hi Bryan,
I did a lot of testing with different compensation circuits and never achieved my goal, so I decided to lower a bit my requirements and designed converter using LM5121.
Thank you for all your support, really appreciate it.

Part Number: LM51551-Q1 Other Parts Discussed in Thread: LM51551 Hello team,
My customer want to confirm the failure mode of LM51551.
1. GATE output not in specification-voltage or timing:
Do this mean the PWM width is wrong or PWM duty is wrong or frequency…
Part Number: LM51551 Hi,

Hi Song,
Sorry for the long delay. To find the source of this error, I would need to look closer into the design. Would it be possible to fill in the quickstart calculator for the LM5155 desing? https://www.ti.com/tool/download/SNVC240
This way I also get…
Part Number: LM51551 Hi Ti experts,
Here is a driver problem that needs your help. Our team designs a 24V to 24V isolation flyback in load 2A. There is a significant spike on Vgs when it is already turned off.
I am trying to use the snubber, cap, and…

Hi team,
my customer wants to know what is the "maximum driving current for external MOSFET"?
they think this 35mA is too small, and they want me to double check internally.

- Iout: 1.3A
I want to design using LM51551QDSSRQ1 and TPL0401V-10 as shown…
Part Number: LM51551 Hello,
I'm trying to design a 100V boost converter using this LM51551 and it's just not working for me.
The conditions are:
Input: +12V
Output: +100V @ 0.3A
Symptoms:
When I plug in the lab power supply, the input voltage…
Part Number: LM51551 Other Parts Discussed in Thread: LM5122 Dear team,
I am looking for 12Vin to 24Vout/5A boost(non-isolated) solution.
And need to have sync pin to control switching frequency(200K~420KKHz), RT pin control have tolerance which not meet…
