This multi-phase design delivers three main performance advantages: Input Protection and EMI Filtering The circuit begins

[AC Input] ──> [Input Protection/Filtering] ──> [Rectification] ──> [Smoothing] ──> [Voltage Regulation] ──> [Stable DC Output] 1. Input Protection and EMI Filtering The circuit begins at the AC input terminal.

In most cases, detailed circuit diagrams for such components are classified or proprietary.

Usually, the MOSFET or the bridge rectifier has failed, causing a short circuit. Unstable Output: Check the feedback network ( VFBcap V sub cap F cap B end-sub ) for burned resistors or damaged electrolytic capacitors.
