パワーマネジメント

A leader in AC/DC RapidCharge™ solutions, Renesas supports more fast charging protocols than any other supplier.

Our patented Zero Voltage Switching (ZVS) technology offers an innovative digital approach to enable 65W+ chargers that are 30% or more smaller than existing "brick" adapters for laptops, monitors, smartphones, power tools and other portable products. Learn More

All of Renesas' AC/DC controllers are hard-wired state machines, so fast chargers designed with them can't be hacked. Learn More

Notes

All primary-side ICs (iW17xx & iW98xx) feature advanced cable fault protection

  1. USB-IF PD Certified (USB PD 3.0 + PPS): iW709, iW657P, iW760
  2. VBUS Switch Driver: Integrated charge pump that drives an external N-channel MOSFET protects VBUS from output short-circuit damage and enables lower cost, easier sourcing vs P-channel
  3. DLNK is Renesas' digital communication from secondary to primary side via an optocoupler
  4. XM-Comm is Renesas' proprietary digital communication via the main power transformer that eliminates the need for an optocoupler
  5. ZVS: Zero Voltage Switching flyback technology
  6. SSR: Secondary-Side Regulation
