Mp3378e Protection Pin Upd Repack Guide
: Used for Over-Current Protection (OCP) . It monitors the current through the inductor to prevent saturation or damage during heavy load conditions.
If an entire LED string becomes open-circuit (broken PCB trace or broken LED), the voltage at the corresponding LED pin drops to zero (or very low). Since the current source cannot regulate current, the boost converter will increase $V_OUT$ to compensate. mp3378e protection pin upd
If one string is significantly brighter or dimmer, the : Used for Over-Current Protection (OCP)
The MP3378E uses a resistor divider from VOUT (boost output) to the PROT pin. If the divider is incorrectly calculated or damaged: mp3378e protection pin upd
