60V 2MHz Buck-Boost Controllers Regulate High Power Voltage and Current with High Efficiency and Low EMI

Keith Szolusha - Applications Engineering Section Leader Aug 24th 2017
Design Note DN567: Introduction Synchronous buck-boost controllers are versatile and highly efficient. They can produce high power as both a boost and a buck with a single inductor, keeping power supply design simple. Normally, a buck-boost controller in a high power application is operated at a standard or low switching frequency, ...

Wireless Current Sense Circuit Floats with Sense Resistor

Kris Lokere - Strategic Applications Manager Apr 25th 2017
Introduction Measuring the current that flows through a sense resistor seems easy. Amplify the voltage, read it with an ADC, and now you know what the current is. But it gets more difficult if the sense resistor itself sits at a voltage that is very different from system ground. Typical solutions bridge that voltage difference ...
