Hi team,
Could you please check the waveform below and comment on why the delay time between VIN and VREG5 is so long? Thanks!
The test condition: VIN= 5V, VOUT= 1.2V and the load= 1.75A.
(We know the PGOOD issue can be solved by connecting the pull-up resistor to VREG5)
CH1:5VSB (VIN), CH2:U57 pin3 (VREG5), CH3:V1P2S_POK (PGOOD) CH4: V1P2S_EN (EN)

Best regards,
