USB PD & Fast Chargers

Fast charger protocols such as USB PD/QC3.0 are dramatically reducing the charging time for a cellphone from an overnight charge to less than 30 minutes. This makes charging more convenient for the user allowing almost continual access to mobile devices.

USB PD is set to become the new standard for charging mobile devices. The USB PD power capability of up to 100 W will make it possible for the user to employ a single charger for cell-phone, tablet and laptop computer.

Introducting InnoSwitch™ - The most integrated and efficient solution for USB PD and fast charging



Combined with the ChyPhy family's simple IC interface, InnoSwitch meets Qualcomm's Quick Charge protocol solution. InnoSwitch also easily interfaces with popular USB PD controllers for USB PD solutions up to 25 W.
