LMR61428 Schematic.pdfLMR61428 Startup Waveforms.zipAs attached are the related layout and schematic. The input voltage range of LMR61428 is 3.5V to 6V, and the output voltage is set as 8V by the resistor divider. Attached waveforms shows the startup waveforms when no load. It shows that the peak voltage goes up to 18V which would damage our IC and the output load (laser lamp). This startup issue happens every startup. Could you give any suggestions to avoid this peak voltage?
Thank you very much.
