By: Mike Becker, International Product and Marketing Manager, Power MOSFETs, Nexperia Low cost power supplies are used in abundance to power a wide range of consumer and industrial applications such as mobile phones, tablet computers, notebook computers, rechargeable power tools and LED lighting, to name just a few. The efficiency of a power supply is […]

Renesas – New Design Support for USB Type-C Applications with ISL95338


Figure 1: Intersil battery charger architecture–dual USB Type-C ports with 2x BB regulator + buck charger The USB-C interface is revolutionizing the way we charge our electronic devices. Physically, the Type-C connector is both bidirectional (either end of the cable can be inserted into either device) and non-polarized (connector can go in either right side […]

Renesas – Latest 15A, 42V Power Module Offers Highest Power Density POL Solution


Figure 1: Inside the ISL8215M power module The DC/DC buck converter is one of the most popular and widely used power supply topologies, finding applications in industrial, servers, telecom, and automotive sectors. The non-isolated buck converter also sees increasing use as a point-of-load (POL) solution to deliver power from a DC bus to individual POLs. […]

Triad Magnetics – Dual-Mode Choke Addresses Differential and Common Mode Noise


By: Lazaro Rodriguez, Standard Product Engineering Manager, Triad Magnetics Circuit designers must deal with many types of noise: internal, external, RF, line frequency and more. Noise can be a limiting factor in system performance and so must be addressed and minimized. The challenge is “at what effort and cost?” Even the ubiquitous switched-mode power supply […]

Vicor – Why are Power Designs Moving to 48V?


Today’s applications are increasing performance by adding: More processing capability Higher communication rates Longer run rates Added peripherals More torque Brighter LEDs To deliver “more” requires more power to be delivered. More power typically is constrained by size and/or weight restrictions. This is why a growing number of industries are moving to higher voltage, 48V distribution versus conventional 12V distribution. […]

Vishay – Generating Isolated Supplies for Industrial Applications Using the SiC462 in an Isolated Buck Topology


By: Ron Vinsant, Vishay Intertechnology, Inc. Introduction Industrial power applications typically require a high input voltage. Standard voltage rails are 24V, 36V, and 48V. The DC/DC step-down (buck) switching regulators and controllers used to power circuitry in industrial applications are required to provide the solid, reliable performance needed for environments subject to noise, power surges, […]
