Power

Power electronics is a key element in the world of electronic design and engineering and electronic engineers need to have a thorough understanding of this area if they’re going to create successful products.

In this section, New Electronics keeps designers up to date with the latest developments in the power electronics market – everything from DC/DC converters to IGBTs to battery technology. In fact, New Electronics covers any power product that can go on a PCB.

XP Power launches 30W medical power supply

The EML30 series of 30 Watt single output ultra compact AC-DC power supplies from XP Power has been designed for use in medical applications. The series comes with what is being described as the smallest footprint and the highest power density in the industry when compared to other similar power supplies with medical safety approvals.

EXTreme Guardian Power Connector system packs high power in a small footprint

Molex Incorporated has announced the addition of 2, 3, 4, 5, and 6 circuit harness connector components to its EXTreme Guardian Power Connector system. The new components include non-overmoulded latching cable receptacle housings, terminal position assurance clips (TPAs), and latchable vertical and right angle headers providing power supply manufactures with more options when designing for the high-current density needs in the computing and telecommunication markets.

POL DC/DC converters target embedded applications

Murata Power Solutions is targeting space constrained embedded applications with the OKDx-T/20-W12 and OKDx-T/25-W12 series point of Load (PoL) DC/DC converters. Designed to provide a combination of high power density and efficiency, the PMBus compatible digital power solution is intended to power CPUs, datacom/telecom systems, distributed bus architectures (DBA), programmable logic, and mixed voltage systems in the networking, computing/servers, telecom, and industrial market sectors.

Transient voltage suppression range expanded

Bourns has made what it calls a significant expansion of its high voltage power transient voltage suppressor (PTVS) product line. Offering bidirectional port protection from 170V to 430V, the nine additional PTVS devices are designed to meet IEC 61000-4-5 8/20µs current surge requirements in a range of AC line and high power DC clamping applications, including exposed AC/DC power supplies in outdoor environments.

Cree adds four 650V SiC diodes to its range

Four 650V SiC diodes have been added to Cree's portfolio. Developed in response to the power supply industry's demand for components with a nominal voltage rating higher than 600V, the Cree Z-Rec SiC Schottky diodes enable high efficiency power systems with improved reliability, simplicity and total cost.

MOSFET drivers come in small packages

Microchip has announced what it says is the first in a new family of power MOSFET drivers. Featuring a new driver architecture for high speed operation, the MCP14A005X and MCP14A015X are available in SOT-23 and 2 x 2mm DFN packages. The small packaging enables higher power densities and smaller solutions, while the design targets fast transitions and short delay times that allow for responsive circuit operation.

Small signal MOSFETs

Diodes has unveiled three small signal MOSFETs in the DFN0606 package. The 20V and 30V rated N-channel transistors and a the 30V rated P-channel device have a footprint of 0.6 x 0.6mm and a power dissipation of 300mW.

400W AC/DC power supplies

A family of 400W AC/DC from CUI is housed in four optional chassis mount case styles, including a compact U-frame measuring 152 x 102 x 38 mm and enclosed versions with top or rear fan options.

Hybrid power modules extended to 3300V and 1500A

Toshiba has extended its family of silicon carbide (SiC) devices with the launch of a 3300V, 1500A power module. The MG1500FXF1US71 plastic case module IEGT integrates an N-channel IEGT and a SiC fast recovery diode into a package with a footprint of just 140 x 190mm.
