Hi Lukas,
LM5123 is not suitable in Class-H system, you should consider LM51231 for single phase version.
We also have LM5126-Q1, it is the single-phase version of LM5125-Q1. LM5126 will be released soon.
I would suggest to consider LM5125 for 42V…
Part Number: LM5171-Q1 Other Parts Discussed in Thread: LM5125-Q1 , LM5171EVM-BIDIR , LM5171
Tool/software:
We are working on an automotive design and are considering using the LM5171-Q1 but have a question regarding the minimum input voltage.
Our…
Hi Lucas,
please have a look at LM5125 https://www.ti.com/product/de-de/LM5125-Q1 .
This part is very new and especially made for audio applications. There will also be a single phase variant available soon.
However, for the negative to negative…
Hi Lee,
The TAS6511-Q1 will not get near the 1000W you want to have. What is the load impedance of your woofer. This will drive your solution. A good power supply IC for class-H is the LM5125.

Hi Guillermo,
I understand that you cannot share the schematic.
I would recommend to have a look at our quickstart calculation tool for LM5122 https://www.ti.com/tool/download/LM5122-BOOST-CALC All equations and calculations are the same for Q1 and…
Hi.
Gwang Seop LIM said: 1. What does "Power Transfer rate" mean?
It means the gain of boost from TRK to Vout, for LM5125 is 30.
For LM5123, it's 20 or 60.
Gwang Seop LIM said: 2. "Target max AVTRK/V" is written as 1.4V.
The Boost Chip…
Hi Angelo,
Angelo Ruotolo said: Reading datasheet , it seems Lm51251A is able to drive more power and more efficiently, while LM51261 usage (Successor of LM51231 previously used) could use less pcb space.
Yes, Lm5125 uses 2 interleaved phases and…
