There's a wonderful expression that people sometimes use to describe a controller chip or power module that looks digital to the outside world, but still employs the fundamental analog control techniques inside. They...
Linear Technology's LT3573 is an isolated monolithic flyback switching regulator with an integrated 1.25-A, 60-V npn power switch. The LT3573 significantly simplifies the design of a flyback converter by eliminating...
If you're hearing less about power-over-Ethernet (PoE) technology these days, it may be because much of the hype that accompanied the introduction of the early PoE components, mainly controller ICs and midspans, has...
Attendees at last week’s Digital Power Forum (DPF) in San Francisco had the opportunity to glimpse some of the latest digital power controller ICs from both established and startup semiconductor companies. The newest...
Yesterday, International Rectifier (www.irf.com) announced the development of a gallium nitride (GaN)-based power device technology platform that promises major improvements in performance over that of conventional...
In diverse applications, digital-control techniques have the potential to reduce component counts, while improving key performance parameters such as efficiency. However, barriers such as controller cost and the...
Good things come in threes. We've all heard that expression. But in power electronics, you could make the argument that good things come in 30s, as in 30 years. Consider that the first commercially successful power...
Panasonic has introduced a high rate lithium-ion (Li-ion) cell that employs a nickel manganese-based cathode material to deliver higher discharge rates and better temperature stability than comparative cells...
The use of Schottky diodes to connect redundant power supplies in parallel for load sharing — a technique known as ORing — offers a simple means of protecting the system against a power-supply failure. However...
