Katelyn,
Knowing the exact problem inside the LM34910 is key to knowing if I have fixed it.
However;
I have a functional solution to the problem where LM34910C fails to start if system leakage voltage appears on the SW pin before Vin is applied. Which…
Part Number: LM34910 We have been into production for years with a board having LM34910 as one of the regulators. This is the main supply (logic circuits, 5V) of the board. The board has a microcontroller and a series of opto-sensors. The total power…
Part Number: LM34910C Other Parts Discussed in Thread: LM34910 , , LMR14203
I am trying ti use the LM34910 as a negative voltage generator/source. While i had been using the LMR14203 successfully for the same purpose, I need to provide more current so…
Part Number: TIDA-00067 What is the actual current/power required for the PA of the AFE031 in the TIDA-00067 design/test? We are working on the same application, PLC over DC power line and are using the AFE031 on the both ends. In the TIDA-00067 design…
Sorry to post in this manner but the site simply is not intuitive as to starting a new question, so;
LM34910 Vin seems to be acting like it has a 7v zener internaly. Key difference between my eariler successful design with the LM34910 is that this time…
Hey Etienne,
Looking at your layout, I think it can be improved. Attached is the sample layout of the LM34910.
With a proper layout, a WEBENCH suggested BOM should work without any intervention. Also, can you can provide scope pictures of the switching…
