Power Integrations announced that its LinkSwitch-II family of power conversion ICs enables manufacturers of cellphone chargers to achieve the recently announced five-star rating for no-load energy consumption.
The new rating system, launched by the world's top five cellphone makers last month, covers all chargers currently sold by Nokia, Samsung, Sony Ericsson, Motorola and LG Electronics. Efficiency ratings range from five stars for the most efficient chargers down to zero stars for units consuming the most energy.
