The standard will cover all products that use external power sources (such as chargers and adapters), including mobile phones, home wireless phones, portable music players, handheld game machines, toys and so on. And require these products to use energy in a more efficient way during standby and use.
This means that after the middle of 2006, all transformers, external power supplies, adapters and chargers used in the United States and to be sold to the United States must change their designs. "The new standard will bring great changes to the current energy ecology," said Doug Bailey, marketing director of Power Integration (PI). PI is the power chip supplier of the above products, and the company is releasing a series of solutions for the new standards to be implemented soon.
"As long as the traditional linear transformer or power supply is connected to the socket, it will consume electricity even if it is not used; Chip power supply does not have this problem. For mobile phones, the adapters of 500 million mobile phones around the world will consume a lot of electricity in standby state, "Bailey said.
From another perspective, this also represents a huge business opportunity. According to the research of Ecos consulting company, there are about 654.38+0.45 billion external power sources in use in California. In 2004, nearly 28 million similar products were sold locally. "These devices use up to 5.548 billion kWh of electricity every year," Bailey said.
In addition to saving energy, the new CEC specification will also have a significant impact on environmental protection. According to the company's statistics, if all external power sources in California can follow the new standards, California will be able to reduce carbon dioxide emissions by more than 360,000 tons per year, which is equivalent to the annual emissions of 60,000 cars.
At the end of 2004, PI introduced a series of high-voltage analog IC solutions LinkSwitch-HF based on its patented EcoSmart technology, which are specially designed for power conversion applications conforming to CEC standards. Its core technology, EcoSmart, is said to greatly reduce the power consumption under standby and no-load conditions, enabling manufacturers to develop products that meet all current and future energy standards.
LinkSwitch-HF is specially designed for mobile phones, digital cameras, PDA, MP3 and other consumer products, as well as industrial and household appliances, with higher integration. It integrates 700V power MOSFET, oscillator, switch control, high-voltage activation, circulating current limit, hysteresis overheating shutdown and automatic restart circuit in a single CMOS chip. Power consumption under no-load is less than 300mW.
