The PS2 Slim relies on several critical voltage rails generated by onboard step-down (buck) regulators. Schematics label these as +5V , +3.3V , +2.5V , +1.7V (for the CPU/GPU core), and +12V (internal power supply models).
There are three sub-revisions of the UPD firmware (1.0, 1.1, and 2.0UPD). The schematic notes that 2.0UPD has a different I²C address for the EEPROM (0xA0 vs 0xA2). Always verify the silkscreen near the UPD chip before swapping boards. ps2 slim schematic diagram upd
