Flyback power converters, Part 2: Enhancements and ICs
Power supplies and converters tend to be simple in principle, yet their actual design – including overcoming the subtle issues which degrade and impede their performance – is the real challenge. In Part 1, we looked at the flyback design and some distinct advantages along with unique idiosyncrasies. This FAQ looks at some of these […]
Rad-tolerant PWM controller/GaN FET driver first to come in a plastic package
Renesas Electronics Corporation announced the space industry’s first plastic-packaged, radiation-tolerant PWM controller and Gallium Nitride (GaN) FET driver for DC/DC power supplies in small satellites (smallsats) and launch vehicles. The ISL71043M single-ended current mode PWM controller and ISL71040M low-side GaN FET driver are ideal for isolated flyback and half-bridge power stages, and motor control driver […]
600-V super junction MOSFETs boast super-fast reverse recovery times
ROHM announced a new lineup of its PrestoMOS series, R60xxJNx series, of 600V super junction MOSFETs that includes 30 new models. This series increases design flexibility while maintaining the industry’s fastest reverse recovery time (trr) optimized for EV charging stations and motor drive in home appliances such as refrigerators and Air Conditioners (ACs). Reports show that close […]
Battery self-discharge and designing for long life
Battery chemistries each have special qualities that can make certain cells impractical for varying kinds of internet-of-things applications. Sol Jacobs | Tadiran Batteries Circuit designers often find themselves in the position of trying to squeeze as much life as possible out of a battery. Today there is much discussion about boosting battery life through use […]
