      New Power Solutions for HDTVs With growing attention on energy conservation around the world, auto companies are not the only ones making the move towards higher efficiency. Every Company in consumer electronics is doing their part in order to adapt to the changing times. As of November 1st, 2008, new Energy Star® [...]

Main Switch Active Clamp Forward Converter Transition Examined

Posted on 01 April 2019

      Understanding the sequence of transitions lead to better design The active clamp topology is one of the more popular topologies in that it allows for efficient conversion of a buss voltage to a voltage needed at the logic ICs in an electronic subsystem. By John Bottrill, Texas Instruments   A review article [...]

Optimising PFC Boost Converter Design

Posted on 01 February 2019

      Simulation model simplifies and speeds topology comparison High power Power Factor Correction (PFC) converters are increasingly important as equipment from welders to uninterruptible power supplies and refrigerators to air conditioners demands powers above 2kW from domestic power supplies. By Cesare Bocchiola, International Rectifier Corp.   And, while bridgeless and other low frequency [...]

Time Controlled Power-Save Mode

Posted on 01 December 2019

      More Flexibility For Low-Power Synchronous Buck Converters Modern synchronous buck converters for portable applications provide so called power-save mode operation to maintain high efficiency over the entire load range. At light loads, the converter operates with pulse frequency modulation (PFM mode) and provides automatic transition into pulse width modulation (PWM mode) at [...]

Power-Save Mode Principles in Low-Power Synchronous Buck Converters

Posted on 01 November 2019

      As with many engineering problems, there is no single best answer Modern synchronous buck converters for portable applications provide so called powersave mode operation to maintain high efficiency over the entire load range. At light loads, the converter operates with pulse frequency modulation (PFM mode) providing automatic transition into pulse width modulation [...]

      Analogue Products Fuel MotionFire Development Platform High performance and efficient analogue content plays an essential role in Arrow’s latest motor control development platform. Electronically controlled motor drives are a vital part of machinery throughout the industrial, medical and automotive environments. Until the introduction of digital systems, motion control schemes relied heavily on [...]

Power Supply Design Made Easy

Posted on 01 September 2019

      Using Integrated Switching Regulators When it came to power supply design, most Engineers would scratch their head thinking, “Where do I start?” Decision must be decided concerning which typology – buck, boost, flyback, half-bridge, fullbridge, etc. How about control scheme, voltage mode, current mode, constant-on, or R3? What is the behavior as [...]

Power Supply Selection Criteria for N+M Redundant Applications

Posted on 01 June 2019

      Redundancy is generally accomplished by paralleling This article provides an overview of the concepts required to enable successful paralleling of AC-DC front end power supplies. Although much of this discussion can be applied to applications which require battery back-up, such as -48V telecom central-office equipment, AC-DC front ends do not typically include [...]

Small Footprint also Occupies Less Board Space

Powering The Next Generation of Digital Television

Posted on 01 May 2019

      The power density of a switch plays a big role Television’s evolution from analog to digital alters the very concept of what a television is. While the main function of a television remains as a method for watching broadcast channels, it has also evolved, becoming a multimedia center in itself. By Mike [...]
