Business of high-powered imitate product develops TI China area manager
Pay attention to safety more
Since this year a series of safe accident happened, for example Sony report core is on the jotter of Dell on fire case, the mobile phone batteries of manufacturer of famous mobile phone explodes in succession etc, chinese government issued the decree with mobile phone mandatory charger. Release TI in succession in semiconductor industry emphasize particularly on charge to protect chip Bq24316 safely to wait, rose to fill the compression of electric government chip considerably at the same time, be like Bq24060, bq24085 built-in press protection too, compression is as high as 26V above.

Pay attention to environmental protection more
The decree of charger of compulsive mobile phone that Chinese government issues what another reason communicates adapter to avoid a mobile phone namely is flush. Low power comsumption stays Electromechanical way gain ground substantially, of road of positive electricity of power factor school use more general. The power factor that each company develops next generation in succession is corrective circuit, the representing's is the two-phase crisscross of TI PFC, UCC28060 and UCC28070, former it is double critical mode, latter is double photograph permanent current mode, still can expand 4 photographs or more photograph. Two-phase or polyphase mode are alternant, reduced ripple not only, reduce the thermal stress of single-phase system, reduced the volume of systematic magnetism material greatly, and reduced cost, raised dependability.
Be paid attention to more and of the system compositive
Simple voltage shift is the market heat of power source no longer. It is with drive of the commonnest Bai Guang LED exemple, TI issued TPS6116x set, its odd input moves smooth control to be able to suit oneself accept PWM, single bus line dictates, imitate voltage, huge went to the lavatory the design versatility of manufacturer of liquid crystal screen.
