Quick Charger

Quick chargers provide rapid charging capability by either raising output voltage beyond 5V with Type-A to Mini-B cable by sourcing larger output current beyond 2.0A through special cables capable of handling the larger current.  Typical quick-charging solutions consist of three major IC performing separate functions: PSR regulation,  SR regulation and protocol decoders. The protocol decoder interprets desired voltage and/or current or other quick-charging related information that is exchanged between chargers and mobile phones.
