Qi-compliant Wireless Power Receiver ICs

IDT’s Qi-compliant wireless power receiver IC s enable OEMs to develop portable devices that are fully compatible with any Qi-compliant charging base. The devices function by converting an AC power signal from a resonant tank into a regulated 5 V output voltage, which can be used to supply power to the mobile system. For the best efficiency, IDT offers compact solutions with an integrated synchronous full bridge rectifier, high-efficiency buck converter, and control circuits. Ultra-compact wireless power receiver ICs swap out the buck converter for a 5 V LDO to minimize PCB area requirements. All devices provide output power up to 5 watts in accordance with the WPC “Qi” specification.

About Wireless Power Receivers

At a high level, wireless power receiver ICs are intelligent devices used to take an incoming AC supply from the receiving coil and convert it into a well-regulated DC supply voltage for use in the system. Wireless power receiver ICs will generally integrate a full-bridge rectifier and linear or switching voltage regulator, along with all the necessary communication and control circuitry necessary to comply with the wireless power standard.
