CYPAS2174
CYPAS2174 is PAG2-PD highly-integrated Power Delivery controller manufactured by Infineon.
description
EZ-PD™ PAG2-PD CYPAS2174 is an integrated secondary-side controller which supports USB Power Delivery extended power range (EPR) mode. EZ-PD™ PAG2-PD is targeted towards USB-C power adapters, it fits well into high-efficiency AC-DC flyback designs with USB Power Delivery, Qualm Quick Charge, and other standard charging protocols. EZ-PD™ PAG2-PD also supports USB PD extended power range (EPR) mode.
Applications
- USB-C chargers and adapters
