  1. Input: EMI filter, fuse, bridge rectifier, bulk capacitor (~100-150µF at 400V).
  2. Switching stage: A MOSFET (e.g., 600V, 3-5A) driven by a PWM controller (e.g., AP3125, LD7575, or a proprietary IC).
  3. Transformer: A small EF25 or EE25 core.
  4. Output: Synchronous rectification (hence "SR" in the name) using two MOSFETs instead of Schottky diodes for efficiency. This would confirm the "BLSR" suffix.
  5. Feedback: An optocoupler (e.g., PC817) and a TL431 voltage reference.
