New TVS diode arrays offer options for both high data-rate interfaces and general purpose applications
03.23.2017 · News
Littelfuse, Inc. introduced an industry first: a new series of three unidirectional TVS diode arrays in space-saving 01005 flip chip packages (0.230 mm × 0.430 mm). Unidirectional protection is typically preferable to bidirectional protection, particularly on logic and data lines, which typically do not transit zero volts during standard operation...

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...

Toshiba Electronics Europe expanded its extensive portfolio of diodes with the addition of six low reverse-current Schottky Barrier Diodes. 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
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...
