Because the 8681L uses a QFN-16 package with a hidden center thermal pad, standard soldering irons cannot be used for installation. A hot-air rework station is required. Required Tools Hot-Air Rework Station (set to roughly High-quality tacky no-clean rosin flux Low-temperature solder paste or fresh leaded solder wire Fine-tipped soldering iron (for pad leveling) Anti-static tweezers and Isopropyl Alcohol (IPA Phase 1: Removal of a Damaged IC

Set your hot air station to with an air velocity scale of roughly 40-50% to prevent dislodging adjacent tiny SMD resistors. 8681l ic datasheet pdf download install
The search term "" for a datasheet is a common misunderstanding. A datasheet is a PDF document for reference and does not require installation. If you encounter an .exe file or a program you are told to "install" when trying to open a datasheet, do not run it . This is a common method for distributing malware.
The power switching node connected directly to the external output inductor. Because the 8681L uses a QFN-16 package with
