input, which is a critical feedback node used to monitor and protect the IC from fault conditions. Protection Pin Overview (OVP)

If an LED string is disconnected or "open," the IC will keep increasing the output voltage. The OVP pin detects this runaway voltage and shuts down the driver once the safety threshold is reached. mp3378e protection pin upd

Disconnect the LED+ and LED- cables from the driver board. Replace with a dummy load (e.g., 1kΩ resistor from SW to GND and a 47kΩ from VOUT to GND). This removes actual LEDs from the equation. input, which is a critical feedback node used

The deep piece of this puzzle is not the copper trace on the PCB, but the concept of . but the concept of .
