The SEPIC topology is generally a good choice for voltage regulators that must produce an on output voltage that falls in the middle of the input-voltage range, such as a 5 V output from a 2.7 to 6 V input. The topology has some disadvantages, however...

Robust 100-V, 1-A synchronous buck converter enables designers to shrink board space, improve efficiency and simplify power-supply design
Texas Instruments introduced a wide-input-voltage synchronous DC/DC buck converter with the industry’s best combination of light load efficiency, ease of design and overall power solution cost...
LED bulbs can bring heat
I had a CFL fail the other day at our upstate house but when I went to the local hardware store to buy a replacement, there was nothing like it to be found. I did find a light emitting diode bulb though so I bought that and installed it with a plastic-shelled adapter having an on/off pull chain like this...
GPIO Port Expander From Diodes Incorporated Provides I2C Interface And Level Shifting For Any Peripheral
Diodes Incorporated announced the PI4IOE5V6416 16-bit I/O expander, which enables any digital device to be accessed and controlled over an I2C interface, across a range of input and output voltages from 1.8 V to 5 V...
Water-Resistant MEMS Pressure Sensor from STMicroelectronics Targets Budget-Conscious Consumer and Industrial Applications
The STMicroelectronics LPS33W water-resistant MEMS pressure sensor combines chemical compatibility, stability, and accuracy for use in a wide range of applications such as fitness trackers and other wearables, vacuum cleaners, and general-purpose industrial sensing...
White-noise generator has no flicker-noise component
White-noise generators generate a flat graph of output-power density versus frequency. These generators are useful for testing circuits that have an extended low-frequency or dc response. However, the presence of pink, or flicker, noise complicates the design of white-noise generators...
Elmos: Low-noise sensor signal processing with SENT interface
Elmos introduces the E520.47, a sensor signal processing IC with SENT interface that supports the simultaneous signal processing of two resistive sensor bridges. The IC has been specially developed for the requirements of automotive applications...
Program a PIC Processor In-Circuit Using a 3.3-V Supply
Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings...
