This component is M2800, aka Trinity. This component is basically a substrate for holding a few coils inside that tend to blow easily.

It includes two backlight coils, one for the Taptic Engine (ARC), one for the Speaker AMP and one for the TIGRIS Buck converter which is used to generate VDD_MAIN from PP5V0_USB (which is provided by whatever power source is connected to the Lightning Port).
