GaN power transistor fits into 5.0 x 6.5-mm footprint May 27, 2015 GaN power transistor fits into 5.0 x 6.5-mm footprint GaN Systems has confirmed the development of the world’s smallest 650 V, 15 A gallium nitride transistor which has a footprint of 5.0 x 6.5 mm making the component 50% smaller than competing devices. Read more Farnell to stock Murata's ultra-compact 1W converters May 27, 2015 Farnell to stock Murata's ultra-compact 1W converters Farnell element14 has introduced Murata’s new NXE1 series of cost-effective 1W Isolated DC/DC Converters into its product lines. With a profile 30% lower than the 7mm height industry norm, the unit is well suited for designs where space constraint is an issue. Read more 60V step-down controller can eliminate intermediate power buses May 26, 2015 60V step-down controller can eliminate intermediate power buses Intersil’s ISL8117 is a 60V synchronous buck controller that can simplify power supply and distribution design; allowing for buck conversions such as 48V direct to 1V – through a very low minimum-on-time-specification – it can permit point-of-load supplies to be fed from 48V rails. ... Read more 48V regulators deliver 100W from a 1-cm-square package May 25, 2015 48V regulators deliver 100W from a 1-cm-square package Vicor has added to its Picor Cool-Power ZVS regulator range with 48V buck regulators that enable direct stepdown from 48V distribution buses to point-of-load with high efficiency. Vicor says that these device increase flexibility for designers and power system architects; as well as regulated-voltage ... Read more Infineon takes CoolMOS to generation 7; halves switching losses May 25, 2015 Infineon takes CoolMOS to generation 7; halves switching losses Infineon Technologies’ C7 series superjunction (SJ) MOSFETs is a 600 V series that claims 50% reduction in turn-off losses compared to the CoolMOS CP, offering a GaN-like level of performance in PFC, TTF and other hard-switching topologies. The company also presents it as a transition to forthcoming ... Read more Digital power chipset optimises dead time automatically May 22, 2015 Digital power chipset optimises dead time automatically Texas Instruments has introduced a power management chipset that includes intelligent digital control and a body-diode sensing feature to optimise secondary-side synchronous rectification in next-generation AC/DC and isolated DC/DC power supplies. Read more 4-ch, 24-GHz downconverter for multichannel, beamforming receivers May 22, 2015 4-ch, 24-GHz downconverter for multichannel, beamforming receivers Analog Devices’ ADF5904 is a highly integrated, 4-channel, 24-GHz receiver downconverter MMIC for which ADI claims the best-available combination of low-noise performance, high linearity and low-power consumption. Read more Double-sided cooling package for Toshiba's 30/60V power MOSFETs May 21, 2015 Double-sided cooling package for Toshiba's 30/60V power MOSFETs Toshiba has expanded its ultra-high-efficiency MOSFET family by adding 30V and 60V devices with dual-sided cooling options; these FETs use the company's U-MOS IX-H trench process deliver high efficiency at all loads and are available in miniature DSOP advance package Read more Auxiliary supplies for industrial designs simplified with PI's LinkSwitch May 20, 2015 Auxiliary supplies for industrial designs simplified with PI's LinkSwitch Providing relatively low power rails to power circuitry in industrial designs can present challenges, when the requirement of meeting the latest efficiency standaerds is added. Power Integrations says it can simplify the design of industrial PSUs for 440-VAC line input using its LinkSwitch-4 device. ... Read more GaN Systems' 60A power transistor sets high point in current handling May 20, 2015 GaN Systems' 60A power transistor sets high point in current handling The gallium nitride device maker claims to now have the highest current GaN power transistor on market at 60A. The GS66516T 650V E-Mode power switch with top side cooling, low inductance GaNPX packaging and ultra low figure-of-merit Island Technology suits high frequency, high efficiency power conversion. ...
