Bi-directional current sense amp targets full-scale direct motor-winding current measurements
Designers can now improve motor efficiency and reduce vibration using the MAX40056 bi-directional current sense amplifier with patented pulse-width modulation (PWM) rejection from Maxim Integrated Products, Inc. Creating a motor control system requires precise current sensing and measurement of motor winding currents. A commonly used approach is to infer winding currents by performing ground or supply […]
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 […]
Flyback power converters, Part 1: Basic principles
Among the many available topologies used for power-supply converters, the flyback design offers some distinct advantages along with unique idiosyncrasies. There’s a wide and diverse array of power-supply converter topologies among which to choose, each with tradeoffs in their various performance attributes and cost. The flyback design is a converter approach which has been used […]
On The Radio: RF Design In The ISM Band
Mastering the groundswell of radio waves The intangible and the invisible electromagnetic spectrum of which radio frequency is a relatively small part is as valuable a natural resource like any other and one which commands our constant attention. From Hertz to Marconi to today’s RF engineers, microwave electronics basics may not have changed dramatically but […]
Four-channel PMIC targets vehicle camera module apps
With automotive camera modules becoming increasingly smaller, designers can now utilize the ultra-compact MAX20049 power management IC from Maxim Integrated Products, Inc. which integrates four power supplies into a tiny footprint. In addition to being the most compact power management IC for vehicle camera modules, it delivers the highest efficiency on the market today. The MAX20049 […]
Heat sinks, Part 2: Available components
Part 1 of this FAQ looked at the basic issues associated with cooling and heat sinks. Part 2 focuses on the various heat sinks available. Q: Are heat sinks limited to a single component such as an IC? A: No, there are heat sinks which fit entire unit or chassis cool such as those which […]
Heat sinks, Part 1: Thermal principles
A heat sink is a non-electronic, passive mechanical component that has a vital role in the reliability and performance of ICs, PC boards, modules, chassis, and more. Heat sinks often don’t get much attention, at least not in the early stages of a design. This FAQ will look at the basic thermal principles of these […]
New IC handles LED matrices with high efficiency
Designers of high-performance automotive matrix lighting and adaptive driving beam light-emitting diode (LED) applications can now migrate to higher current devices while reducing solution size and improving flexibility with the MAX20092 12-switch matrix manager from Maxim Integrated Products, Inc. The IC minimizes thermal issues associated with LED matrix lighting applications by offering the industry’s lowest internal switch […]
