Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Internally adopted synchronous rectifier control helps for less BOM counts as well as for easy design. FAN6291QF/FAN6291QH are also a source only USB Type-C 14 1 14 controllers which are optimized for mobile chargers and power adapters. TSSOP-14 It supports standard 3 A VBUS current level. N-Channel MOSFET is compatible as a load switch, and helps to reduce BOM cost. MARKING DIAGRAM 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. ZXYTT 6291QX FAN6291QF/FAN6291QH enables adaptor output voltage and current MTCF 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 non- compliant protocols is attached, it just maintains the default output, (5 V) st for safety of the portable device. 1 Line: F: Corporate Logo Z: Assembly Plant Code FAN6291QF/FAN6291QH incorporates adaptive output over-voltage and X: Year Code under-voltage protections to improve system reliability.
