8682l Datasheet ^new^

The (also known as the OZ8682L or OZ8682LN ) is an integrated circuit developed by O2Micro . It is primarily used as a DC/DC converter and battery charger controller , frequently found in laptop motherboards like the Apple MacBook Pro A1278 (Early 2011). Key Specifications & Features Manufacturer: O2Micro Package Type: QFN16 (16-pin Quad Flat No-lead)

: Prioritizes power to the host system. If the system demands more current, the 8682L dynamically throttles the battery charging rate to prevent the AC adapter from overloading. Technical Specifications & Absolute Maximum Ratings
