Power Supplies
Power Tip #1: Picking the right operating frequency for your power supply
Low-frequency designs tend to be the most efficient, but are the largest and most costly. Moving higher in frequency improves size and cost at the expense of circuit losses.
Building a power supply for discontinuous transmission wireless networks
Need to reliably power a remote control for electromechanical actuators and electronic sensors in harsh environments? Here's the design for an isolated, switched-mode power supply intended for wireless devices.

How to select effective ESD protection diodes
Key DC specs on protection diode datasheets are breakdown voltage, leakage, and capacitance. They also state a max rating for IEC61000-4-2 to indicate an ESD pulse at a specified level will not damage the diode. However, most datasheets do not have any information about the clamping voltage for high-frequency, high-current transients such as ESD.
Tip of the Week: Adding over-voltage protection to your mobile/portable embedded design
How to use the ON Semiconductor's NCP347 and NCP348 to protect device electronics from over-voltage spikes from either the internal battery or an external power supply.
