Other Parts Discussed in Thread: LM26420,
Hi LM26420-Q1 When testing the output SW of LM26420, the test found that the SW waveform overshoot and undershoot are very serious, the undershoot reaches 1.05V, the overshoot is 0.7V, the input is 3.3V, and the two outputs are 1.8V and 1.8V respectively. 1.1V, the load is 0.5A~0.6A. Please help to check the schematic, is there any solution to solve the overshoot and undershoot?
