This chip regulates the output voltage by controlling the duty cycle of the MOSFETs based on feedback from the output. Thermal Control 90–132 VAC / 180–264 VAC (Selected
: In case of an overload (105%-150% of rated capacity), the supply reduces its output to prevent damage, often featuring auto-recovery once the fault is removed. Thermal Control Understanding its internal circuit design
