Impact: Check that the new voltage rails start order power-up sequence fits your requirements. Voltage supervisor (U4) enables 1V voltage rail (DCDC U23) via signal EN_Module. 1V DCDC (U23) enables 1.8V voltage rail (DCDC U25) via signal PG_1V0. 1.8V DCDC (U25) enables 2.5V (DCDC U24) and DDR_VDD (DCDC U26) voltage rails via signal PG_1V8. Voltage rail 3.3V (load switch Q1) is logical AND-enabled via power good signal PG_2V5_3V3 from voltage rail 2.5V DCDC (U24) and DDR_VDD DCDC (U26) via diode (D4) and CPLD (U6) signal EN_3V3 via diode (D5).
