Primary-Side CC/CV Flyback Controller with 700V Current Source

February 17, 2017

The MP023 from Monolithic Power Systems is an offline, primary-side controller that provides accurate, constant voltage and constant current regulation without the need of an optocoupler or secondary feedback circuit. It uses an integrated 700V current source to achieve quick start-up. It is designed to operate over a line voltage range of 85- to 265-Vac with a maximum switching frequency of 75kHz. The MP023 incudes programmable cable compensation.

Optimizing Power Conversion from 100pA to 1mA

Friday Feature

February 17, 2017

Wireless sensors on the Internet of Things (IoT) will have to operate at very low powers, in order to extend battery life for months or make do with energy harvested from the environment. But that means that they'll need to draw a wide range of electrical currents. A sensor might, for instance, wake up every so often, take a measurement, and perform a small calculation to see whether that measurement crosses some threshold. Those operations require relatively little current, but occasionally, the sensor might need to transmit an alert to a distant radio receiver. That requires much larger currents.

The Future of Electricity

Richard Zhang
Technology Executive, GE Power Conversion

We are living in a dynamic global power environment. We all need the same thing—affordable, sustainable, reliable power, and the demand is growing. While the power sector is leading the way towards a decarbonized energy system, electricity gains ground in many sectors and will make up about 25 percent of final energy consumption by 2040, as estimated by IEA.
