FAN6290QF is a highly integrated, secondary-side power adaptor controller compatible with the Quick Charge 3.0 (QC3.0) protocol. Internally adopted synchronous rectifier control helps for less BOM counts as well as for easy design.FAN6290QF is also a source only USB Type-C controllers which are optimized for mobile chargers and power adapters. It supports standard 3 A VBUS current level. N-Channel MOSFET iscompatible as a load switch, and helps to reduce BOM cost.The internal two operational amplifiers control adaptive constant output voltage and adaptive constant output current. The outputs of the two amplifiers are tied together in open-drain configuration.FAN6290QF enables adaptor output voltage and current adjustment when Quick Charge 3.0 protocol is acknowledged. According to request from a battery charger of a Portable Device, output voltage is adjusted up to 12 V. When a portable device that implements noncompliant protocols is attached, it just maintains the default output, (5 V) for safety of the portable device.FAN6290QF incorporates adaptive output over-voltage andunder-voltage protections to improve system reliability.
