Primary side capacitors hold lethal charge even after unplugging. Discharge via 10kΩ 5W resistor before handling.
: Often utilizes a dedicated PWM controller IC (like the LD75xx or OB series) to drive a switching MOSFET. Output Rails : Typically provides +12Vpositive 12 cap V (for audio/backlight drive) and +5Vpositive 5 cap V (for standby and processor logic). 2.
