4. The LTC3119 buck-boost converter IC is housed in a thermally enhanced, 28-lead, 4- × 5-mm QFN or TSSOP package. Capacitor Selection. A low-ESR (equivalent series resistance) output capacitor ...

A synchronous buck-boost converter IC from Linear Technology builds on the success of the company’s LTC3440 by extending that device’s input voltage range and by making burst-mode operation ...

The module under the knife is a popular buck-boost converter with a wide input range, 0-32 VDC output at up to 5 amps, and a fancy controller with an LCD display.

Texas Instruments (TI) has introduced a bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA. The TPS61094 integrates a buck mode for supercapacitor charging while ...

Even though buck converters, and other DC converters like boost and the mysterious buck-boost converter, seem like magic even to us, there is some interesting electrical theory going on if you ...

Super cap back-up buck-boost converter idles at 60nA 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 ...
