Limits current to the external MOSFET and internal buck converter. mp3378e protection pin upd

If the backlight flashes and then turns off, the IC has likely detected a fault (e.g., an open LED string) and triggered its internal protection. mp3378e protection pin upd

The MP3378E integrates multiple protection modes to safeguard the IC and the LED strings from damage: mp3378e protection pin upd

Over-Voltage Protection input; senses output voltage via a resistor divider.

Enables the IC and controls brightness via pulse-width modulation.
