Hello,
Can LM5143-Q1 accept ac coupled frequency sync signal? I'm designing an inverting buck-boost power supply using this device. Do I need to level shift frequency sync signal to -Vout?
Thanks,
Shaury

Hi Shuary,
The SYNC signal should be referenced to AGND of the controller, which corresponds to -Vout of the IBB.
