Sn51dp Datasheet High Quality [portable]

If the backlight is too bright or consuming too much power, engineers can employ two primary methods to adjust the LED current:

At its core, the SN51DP functions as a high‑efficiency switching power supply that converts a 12 V or 24 V input into a regulated, often much higher voltage to power the LED strings of an LCD panel. Typical output voltages reach 72 V or more, and in many designs the output stage includes an external MOSFET, inductor, and rectifier diode to achieve the required boost conversion.
