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…
Hi Jaye,
I followed up with the Webench team on this model. The Webench was taken down in the 2015, and currently, there engineers are working on bringing this model back to TI.com. They are currently retesting the model, and they are targeting to…
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…
Well, I think I solved the issue. Seems that the LM34910 does not apprecieate 200 Ohm resistive load attached to the inductive output filter. When I increased the resistor value to >2K then the Vin was not clamped near 7v. Along the way I noticed that…
Part Number: TIDA-00067 Other Parts Discussed in Thread: LM34910 , AFE031 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…
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…
Hello Steven and thank you for your interest in Texas Instruments. The reference design that this is tied to is no longer active and obsolete. However, I was able to locate the collateral you are interested in.

Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
