DIODES™ AP33771 USB PD Sink Controller

High performance for the new standard

DIODES™ AP33771 is a highly integrated USB PD Sink Controller that leverages and raises the increasing popularity of Type-C connector-equipped devices (TCD) as a standard. Targeting the DC power requests for TCDs, this device negotiates with PD3.0 adaptors to acquire and distribute power to supply the TCD.

Up to eight voltages can be selected for the DIODES™ AP3377. Besides, the device’s search algorithm supports both fixed PDO and PPS APDO in the PD source adapter. In addition, up to ten maximum power levels can be selected through a variety of resistance values.

Reduce total BOM and maintain maximum flexibility with a device that brings the new standard to a new height.
