This overview will help you identify your iPhone original USB charger . When you need to charge your iPhone or iPad, we recommend that you use the USB power adapter and USB cable that come standard with the standard. These adapters and cables are also available separately from Apple and Apple Authorized Resellers. For details on charging your iPhone or iPad, please refer to the “Safety, Operation and Support” section in the iPhone User Guide or iPad User Guide.

Energy conservation and consumption reduction is not only a technical aspect of current electronic technology, but also plays a key role in promoting government economic growth. Therefore, from CEC, ENERGY STAR to China's "1 watt plan", objective demand and government orientation are two-pronged, affecting the increasingly energy-saving of electronic technology. Power chip manufacturers are also launching a series of energy-saving products. For the various mobile phone charger manufacturers looking to design the latest energy efficiency standards, Power Integrations (PI)'s latest TOPSwitch-HX series is a good choice.       Multi-mode control force, change efficient hotspots as highlights       TOPSwitch-HX integrates 700V switching power MOSFETs, controllers and monitoring functions on a single IC and uses PI's patented EcoSmart energy-saving technology. Having excellent standby power consumption and consistently efficient operation under all load cond...

Power adapter , can not be separated from our lives, such as mobile phone charger, mobile power, LED lighting, etc., we discuss the history, background, research scope, current status, future development direction and current controversy focus of the power adapter, the purpose of the research Meaning, importance. At the end of the 19th century, Thomas Edison successfully used a direct current transmission to light up the light bulb, but because of the huge energy loss, the efficiency of direct current transmission is very low. In 1957, JenSen invented the self-excited push-pull double transformer. In 1964, American scientists proposed the elimination of the series power adapter of the power frequency transformer, which made the power supply a fundamental way to reduce the volume and weight. . Later, Nikolates invented the AC transmission, which replaced the DC transmission. In 1969, due to the improvement of the withstand voltage of high-power silicon transistors and the shortening o...
