Here's how to convert a positive 10 -- 50V input to a minus 10V output Design How-To 3/19/2006 Post a comment Buck regulators are commonly used to efficiently step down a higher level, unregulated, positive input voltage to a regulated positive output voltage. A Buck regulator can be reconfigured into a Buck-Boost regulator to convert a positive input voltage to a negative output voltage. Find out how the challenge of accurate and fast current measurement can be avoided with a new method that emulates the buck switch current without actually measuring the current.

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
