The Top 10 Most Popular Power Management Technical Articles of 2012
Beginning in reverse order we have:
10. Design a wide-voltage-band buck regulator
Michael Harney described the design of a wide-band buck regulator, which is a standard buck regulator, but with modifications that allow the output voltage to vary across a wider range. This allows it to accommodate electronic devices that also operate over a wide range.
9. Power Tip 53: Use P-SPICE to design your power supply control loop
Robert Kollman of Texas Instruments focused on how to P-SPICEcan be used to design a power supply control loop.
8. Reduce THD in digitally-controlled PFCs
Bosheng Sun and Zhong Ye of Texas Instruments examined the most common methods to reduce the current distortion in a digitally-controlled PFC.
7. FRAMs as alternatives to flash memory in embedded designs
Priya Thanigai of Texas Instruments discussed key technology attributes of FRAM while exploring specific use cases that demonstrate FRAM’s advantages.
6. Calibrate a power supply with a digital potentiometer
David Fry, Strategic Applications Manager, Maxim Integrated Products outlined a calibration solution for a power supply that uses a digital pot to create an optimal design.
5. Ruggedize USB connections for tough environments
Brian Foster of B&B Electronics Manufacturing Co. examined the requirements to ruggedize USB connections for tough environments.
4. No magnetics required – charge pumps can handle the volts
Steve Knoth Senior Product Marketing Engineer, Power Products Group Linear Technology Corporation examined the benefits of using charge pumps to provide versatile application solutions.
3. Understanding wire-less charging
Coming in third place was Markus Huschens who is New Business Research Manager at Murata Electronics Europe. His article focused on the increasing popularity of battery-powered consumer electronic devices such as portable media players, smartphones and tablets which has led to a host of different chargers and a tangle of wires littering the home. The concept of wirelessly charging the devices, i.e. without any direct-wired connection, has been around for a while but is now rapidly gaining interest to make it more flexible and useable. But what are the different techniques available, and what are the design challenges an engineer needs to deal with?
2. Simple circuit measures RMS value of AC power line
In second place Chau Tran and David Karpaty of Analog Devices Inc. described a simple circuit that is capable of measuring the RMS value of an AC power line.
1. A Current Sensing Tutorial – Part 1: Fundamentals
And finally the most popular Power Management article of 2012 was authored by Pete Semig and Collin Wells of Texas Instruments who examined the fundamentals of current sensing, including direct versus indirect sensing, input common-mode voltage, high versus low-side sensing, directionality, and output requirements.
