LM34966-Q1: AHB solution searching

Zhenyu Chen

Part Number: LM34966-Q1
Other Parts Discussed in Thread: LM5155, UCC28600, TPS92210

I have a application with the input condition from 9V~16V and output with 60V/0.6A. And isolation is needed, is there some AHB solution for this?

if not, is there some ACF or QR flyback solution for this? please give me some proposals.

thx!

Hi Zhenyu,

Thanks for using the e2e forum.

LM5155 in isolated flyback topology should be suitable for this application.
A reference design for this can be found here:

Best regards,
Niklas

hi Niklas,

thanks for you feedback. but i need the AHB or QR/ACF soft-switching solutions, because i need to set the switching frequency as high as possible so that reduce the size of the magnetic component.

do you have some furhter proposals?

Hi Zhenyu,

Thanks for the update.
All the devices from our portfolio run with fixed switching frequency, so a soft-switching solution like QR-Flyback is not possible.
There are parts from different product lines, which might have more suitable parts for this.

Here are two controllers which might be a better fit:
UCC28600 https://www.ti.com/product/de-de/UCC28600
TPS92210 https://www.ti.com/product/de-de/TPS92210

Unfortunately, I am not an expert for these devices, so if there are questions on these parts, it would be faster to set up a new e2e ticket.

Best regards,
Niklas
