  • Autonomous USB Power Delivery Rev. 3.0 (PD3.0) v1.2 and Type-C™ Rev. 2.0 compliant
  • Programmable Power Supplies (PPS) solution for DC-DC and AC-DC applications
  • Very low active power, highly power efficient
  • Built−in cable−drop compensation

The FUSB3307 is a fully autonomous Rev. 2.0 Type-C and Rev. 3.0 Power Delivery-compliant power source controller. It can control a DC-DC port power regulator such as the NCP81599 or an optocoupler on the secondary side of an AC-DC adapter. It implements the source finite state machines of USB Power Delivery 3.0 (PD3.0) and Type-C which includes Programmable Power Supplies (PPS).
