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.

Power Integrations' InnoSwitch™ Family of ICs offer an integrated and highly efficient solution

for USB-PD and fast charging. InnoSwitch ICs combine primary, secondary, and feedback circuits

in a single surface-mounted off-line flyback switcher IC.

InnoSwitch ICs feature the following:

• Primary FET and controller
• Secondary-side controller for synchronous rectification
• New FluxLink™ technology, eliminating the need for an optocoupler
