USB Type-C DFP with Charging Port Controller and Integrated 36V 3.5A ,Synchronous Buck Converter
The RTQ2116C combines a USB Type-C Downstream Facing Port (DFP) controller, ,charging port controller and a 3.5A synchronous buck converter.,,The RTQ2116C monitors the Type-C Configuration Channel (CC) lines to detect ,an Upstream Facing Port (UFP) device attach event, then turns on external VBUS ,MOSFET to apply power to VBUS and communicates the selectable VBUS current ,sourcing capability.,,The RTQ2116C provides the electrical signatures on D+/D- to support charging ,schemes compatible with the USB 2.0 Battery Charging Specification BC1.2 and ,Chinese Telecommunication Industry Standard YD/T 1591-2009. Auto-detect mode is ,also integrated which supports USB 2.0 Battery Charging Specification BC1.2 ,Dedicated Charging Port (DCP), Divider 3 mode and 1.2V shorted mode to comply ,with the legacy fast charging mode of mobile devices.,,The RTQ2116C integrates a high efficiency, monolithic synchronous buck ,converter that can deliver up to 3.5A output current from a 3V to 36V wide ,range input supply and is protected from load-dump transients up to 42V.,,The RTQ2116C has constant current control to achieve adjustable USB current ,limit and implement the current sense signal for adjustable USB power output ,voltage with load line compensation. The converter includes optional ,spread-spectrum frequency modulation to overcome EMI issue and complete ,protection for safe and smooth operation in all applied conditions. Protection ,features include cycle-by-cycle current limit for protection against shorted ,outputs, soft-start control to eliminate input current surge during start-up, ,input under-voltage lockout, output under-voltage protection, output ,over-voltage protection and over-temperature protection.,,The RTQ2116C is fully specified over the temperature range of TJ = -40°C to ,125°C and available in WET-WQFN-40L 6x6.,,The RTQ2116C can be used to support Type-C connectors including the Type ,C-to-C dongle and the Type C-to-B dongle. Type-A connector support is provided ,by the RTQ2116C.,,
