Hey all,
I have fabricated a PCB with the LM5157-Q1 see the attached schematic. This schematic was review and blessed by TI in another thread. It is working fine at a 2.841A load but when increased to a 3.055A load the regulator can not keep up, see attached screen shot. Anything I can do to be stable at a higher load?
Sincerely,
Corey
Hi Corey,
Thank you for using E2E forums, Could you please fill this excel sheet for your schematic design https://www.ti.com/tool/download/SNVR511 ? Also, could you explain the waveform as to what am I seeing there? is the CH1 your Vout? what is Ch2? Could you also share your SW node waveform?
