The MP3378E is housed in a 28-pin TSSOP package with an exposed pad for heat dissipation. Primary Function
Technicians often check the resistor values for the OVP resistor divider to ensure the chip is receiving the correct feedback voltage. Troubleshooting and "Bypassing" mp3378e protection pin upd
Sets the LED current; a resistor between this pin and ground programs the brightness. The MP3378E is housed in a 28-pin TSSOP
