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.

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.

Single cell battery charger for auto applications

Intersil has announced the ISL78692, a 4.1V single cell battery charger designed to extend the life of Li-ion batteries in automotive emergency call systems. The ISL78692 battery charger has a lower leakage current – said to be 3µA – than competing solutions, allowing the backup battery to remain charged for a longer period. Lower charging voltage also extends battery life, whilst the device's small footprint reduces total solution size.
