GPU fans spin, RGB lights up, but no display. The PCIe slot detects the card, but the voltage on the Vcore rail is 0V.
The Soft-Start feature is essential for protecting the load. Without soft-start, the schematic would show a massive inrush current at startup as the output capacitors charge. The ADP200ER schematic includes an internal current source and a capacitor (or an internal digital counter) that ramps up the reference voltage gradually. This "exclusive" internal architecture ensures that the output voltage rises in a controlled linear ramp, eliminating inrush current stress on the input power source. adp200er schematic exclusive
