03.20.2017 · News
Texas Instruments introduced a digital-to-analog converter that combines industry-leading precision performance with simpler power-supply design. The 16-bit DAC8775 operates from a single, wide 12- to 36-V power rail, leveraging an integrated buck/boost converter to generate all of the required internal power supplies to save designers time, cost and significant board space...
Thermal design: Get the heat out of the electronics
03.17.2017 · Articles
If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is to bolt your power transistor to an aluminum heat sink. That is a slow, messy, and expensive proposition, especially if you need thermal grease between the transistor and heat sink...

With a peak reverse voltage of 40 V, the new CCS15F40, CUS15F40, CBS10F40, CUS10F40, CTS05F40, and CUS05F40 are suitable for voltage boosting circuits in white LED backlights and for liquid crystal displays in mobile devices like smartphones and tablet PCs...
Buck-boost regulator suits battery operation
03.16.2017 · Circuits
A buck/boost converter can step a voltage up or down. Such a converter is appropriate for battery-powered applications. One application derives a regulated 14.1 V at 1 A from 12 V solar panels with 9 to 18 V variation. In this type of battery application, efficiency is an important factor; hence, this design uses an inexpensive synchronous-rectifier-based MC33166/7 circuit...
