尽管锂离子电池可为最新一代的移动电话提供高能电源,但就单位成本和安全性来说,它们还远远达不到理想要求。一种独特的新款DC/DC变换器芯片由欧洲最大的半导体制造商飞利浦半导体公司推出,它允许设计者采用两枚AAA镍镉或镍氢电池来代替锂离子电池,以减少单位成本并增加安全性,同时不影响电话大小、重量和性能。在美国Santa Clara的Power’98展会上,飞利浦半导体推出的TEA1210输出脉冲功率可达 Although lithium-ion batteries provide high-energy power for the latest generation of mobile phones, they are far from ideal in terms of unit cost and safety. Introduced by Philips Semiconductors, Europe’s largest semiconductor maker, a unique new DC / DC converter chip allows designers to replace two lithium-ion batteries with two AAA nickel-cadmium or nickel metal hydride batteries to reduce unit costs and increase safety Without affecting phone size, weight and performance. At the Power’98 show in Santa Clara, USA, the TEA1210 from Philips Semiconductors has output pulse power up to
