What is this chips part number
I need to know what this chip is, it was water damaged on my board, and the pads wont take any solder, so i need a new one, but i can't read the name of the chip anymore. Any one know the name of the chip?
jeremy, right now, with the limited information I have about your logic board, it appears that the IC is REFERENCE DES U9701 PROD DESCRIPTION IC,LP8543,WHT LED BKLT CTRLR,QFN24. The LP8543 is a white LED driver with integrated boost converter. It has 7 adjustable current sinks which can be controlled by SMBus or I 2C-compatible serial interface, PWM input and Ambient Light Sensor (ALS). That datasheet for that is available right here. they are a little hard to come by as a single piece. You can purchase quantity of 10 from here. There are some on sale right here as well as ebay.com. If there is any change after you positively identify the motherboard for me, I will let you know as soon as possible. Hope this helps, good luck.
