Part Number: LM5146 Tool/software: What are the figures in the two red boxes in Figure 1 on the M5146RGYR DIE? Will it cause a short circuit between the chip and the external ring?
What is this ring at the edge of Figure 2?
Hi Timothy：
The test conditions are 48V input and 24V output. The waveform of the LM5146 no-load test is shown below.
Switch SW test waveform:
High side MOS tube HO test waveform:
Low side MOS tube LO test waveform:
Dual channel testing of HO and LO…
