Hey Ethen,
Thanks again for your guidance earlier.
As of now, we have replaced the IC with a new one. also replaced the FETs which shown short circuit.
the charging configuration that we made for 48 V input is as follows :

Part Number: LMG2100R044 Other Parts Discussed in Thread: LMG2100EVM-078 , TIDA-010936 , TIDA-010933 Tool/software: Hi TI Experts,
I am currently testing my pcb using LMG2100 for buck-boost converter. I face a big issue that damage the LMG2100, I had…
Part Number: TPS92692 Tool/software: Dear
Use TPS92692 for BOOST constant current, we want to use the enable voltage of the PWM pin to create a simple low-voltage turn off limiting circuit (as shown in the figure below, our calculation shows that it…
Hi Ulrich
Thanks for the email
We have miscommunication I am not looking at the PMP9730
I am looking at UCC28051 ref design below
100-W Universal Line Input PFC Boost Converter Using the UCC28051
Please look at the user guide (sluu152a) schematic…
Hi,
It looks to me the reason is like the below:
The sensing on R8 needs to reach 2V, to match U3 ref 2V. 2V on R8 produces 2A which also flows through R12. So the resulted Vout = 4V < 30Vin.
The converter is in the boost topology not able to regulate…

Hi Christian,
The control of BUBO is very different with boost converter. please do not take the TPS61033 as ref.
For TPS631010, there is a mode seletion pin, when MODE pin is high level, the device will work in FPWM mode, which menas, no matter the…
I also tried connecting EVM to GUI tool. Reset, enabled Internal ref, Enabled Buck boost converters, enabled Output and wrote values as FFFF in DAc data registers. I'm able to Readback the wrote value as FFFF.
But Vout was 0. I then read status of Reset…
Hi Denny,
Thank you for reaching out. Yes this can be supported by a boost controller or converter in the inverting buck-boost configuration like shown in the following ref design:

Obviously the ref design has a…
