Help identifying component

[JMCD]

Hiya, well my google fu has failed me...

I'm on a quest to understand my LCD driver a little more. It's a PCB800852.

Specifically the backlight driver portion. In the hopes of modding/replacing it to be more efficient and offer variable brightness from within software.

Can anyone help id the ic highlighted please? I'm trying to find a datasheet for it.

Many thanks!

For completeness I'll update this in case anyone else is looking.

I've managed to ID the model and manufacturer.

Diodes Inc
AP3019AKTR-G1

Looking at the datasheet, it would appear we have a few methods of brightness control.

Either PWM on the CTRL pin or by altering the DC voltage on the FB pin.

I'll update once I've explored both methods.
