Many of today's MP3 players, multimedia players, digital video recorders, and other portable electronic devices have found the micro hard disk drive to be the optimum device for memory storage ...

Buck-boost converters are popular solutions to cope with a wide-input voltage range that fluctuates below or above the desired output voltage. The conventional two-switch buck-boost converter offers ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...

Modern portable applications require batteries with higher power densities. Battery chemistries such as nickel metal hydride (NiMH), Lithium-ion (Li-ion), and Lithium-polymer (Li-poly) have adequately ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China (USTC ...

For those living before the invention of the transistor, the modern world must appear almost magical. Computers are everywhere now and are much more reliable, but there are other less obvious changes ...
