ChiPhy Family

To meet the need for adaptive rapid charging systems, Power Integrations has developed the "ChiPhy™" (charger physical interface) family of ICs. Used in combination with one of Power Integrations' AC-DC switcher ICs, such as TOPSwitch or TinySwitch, ChiPhy ICs add adaptive rapid charging functionality to AC-DC wall chargers.
