Several power supply topologies, including SEPIC and flyback converters [1], generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the ...

Texas Instruments has introduced an IC to mediate between a power rail, a load and a back-up supercapacitor. All the time sufficient voltage is available at the input, the input is connected directly ...

A buck-boost converter maintains a regulated VOUT regardless of whether VIN is above, below, or equal to the output voltage. Ideally, the change from buck to boost and vice versa takes place ...

Texas Instruments' TPS63000 helps extend battery life in smart phones, digital still cameras and other single-cell, Li-ion-powered devices by providing high-efficiency buck-boost power conversion.

KYOTO, TOKYO and SANTA CLARA, CA--(Marketwired - March 17, 2016) - ROHM has recently announced the development of the BD51180TL, a step-down DC/DC converter featuring the lowest minimum ON time in the ...

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 ...

Maxim Integrated has introduced the Max77827, a buck-boost converter featuring a quiescent current (IQ) of 6µA and peak efficiency of 96%. It addresses the power requirements of low-power wide-area ...

The SPI-8010A is a high-efficiency (94%), adjustable-output, 3-A buck converter IC, available in an HSOP16 package with enhanced thermal-dissipation capability. The package's special ground-potential ...

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 ...

Generally when you crack open a cheap car-to-USB charger unit that came with some widget, you do not expect to find anything amazing inside. That’s why it was such a surprise to [Big Clive] when said ...
