The Standby Circuit: A small circuit that provides a continuous 5V to the PS4 motherboard, waiting for the power button to be pressed.
- Schottky Diodes (D2, D3): Large, fast-recovery diodes (e.g., MBR20100CT) that rectify the high-frequency pulses from the transformer into DC.
- Output Capacitors (C10-C13, 680µF/25V): Multiple capacitors in parallel to lower ESR and smooth the 20V output.
- Output Inductor (L2): Small coil for additional filtering.
, which powers the console’s basic functions and standby mode. Main Rail Output: +12V at 13A
