https://restoreredspruce.org/2024/05/13/mxm2l95pmzq The MP3378E is a one-chip solution specially designed for monitor applications. The MP3378E includes a step-up WLED controller with four current a high-efficiency buck converter for internal bus channels for backlighting, and voltage or standby power.
The 4-string WLED controller drives an external MOSFET to boost up the output voltage from the input supply. It regulates the current in each LED string to the programmed value set by an external current setting resistor. It supports both analog and PWM dimming independently to meet special dimming mode requests. Full protection features for the WLED controller include OCP, OTP, UVP, OVP, LED short/open protection, and inductor/diode short protection.

watch The high-efficiency buck converter operates in the current mode operation with a built-in MOSFET and a built-in synchronous rectifier. It offers a very compact solution to achieve excellent load and line regulation. Full protection features for the buck converter include OCP and thermal shutdown.
