The marking is typically a specific manufacturer's part number or date/batch code often associated with PWM (Pulse Width Modulation) Controller ICs . In many contexts, this marking corresponds to the LD7575 or similar generic SMPS controllers.
When replacing a defective chip using a hot-air rework station, technicians must account for the alloy profile:
