eGaN power devices now available in wafer form
EPC announces the availability of their enhancement-mode gallium nitride (GaN) devices in wafer form for ease of integration. EPC’s eGaN FETs and ICs are traditionally sold as singular chip-scale devices with solder bars or solder bumps. Chip-scale packaging is a more efficient form of packaging that reduces the resistance, inductance, size, thermal impedance, and cost […]
GaN process supports mmWave and 5G power applications
WIN Semiconductors Corp has expanded its gallium nitride (GaN) portfolio with the commercial release of a 0.15μm-gate technology, NP15-00 Gan process, that supports emerging mmWave PA applications including radar, satellite communications, and 5G massive MIMO infrastructure. The NP15-00 GaN process technology supports full MMICs enabling WIN customers to design compact, linear or saturated high power […]

16-channel current driver integrates 4-bit decoder for satellite applications
Renesas Electronics Corporation announced a new radiation-hardened 16-channel current driver with integrated 4-bit decoder for reducing the size, weight and power (SWaP) of satellite command and telemetry systems. The ISL72814SEH integrates the decoder, input level shifter, and 16 current driver arrays in a single monolithic IC. The device allows satellite manufacturers to significantly increase system […]
Regenerative electronic loads deliver savings in power supply burn-in testing
by Eric Turner, Elektro-Automatik, USA The introduction of regenerative electronic loads has dramatically altered the economics of power supply burn-in testing. This article describes how the use of advanced technology, regenerative electronic loads resulted in energy cost reductions exceeding 90 percent. In addition to the lower energy costs, the use of regenerative loads has also […]
Why it’s tough to characterize SiC power MOSFETs
Switching transients and parasitics can combine to thwart the accurate measurement of important MOSFET operating parameters. Levi Gant, Xuning Zhang, Ph.D., Littelfuse, Inc. Silicon carbide (SiC) power MOSFETs get a lot of attention because they can switch fast while maintaining high blocking voltages. But their superior switching qualities also have potential drawbacks. Parasitic inductances caused […]
Thin-film power inductors boast rated inductance of 1.0 µH
TDK Corporation announces the development of a miniaturized thin-film power inductor in an IEC 2012 case size that can handle higher currents compared to conventional products. The low-profile TFM201208ALD power inductor measures in at 2.0 x 1.25 x 0.8 mm and is available with a rated inductance of 1.0 µH. Thanks to its reduced DC […]
An overview of fan bearing designs
by Ryan Smoot, CUI Fans are a crucial feature of many electronic systems, maintaining operation within a certain temperature range, while ensuring electronics are working at their optimum level across their operational lifetime. Key to a fan’s design is the consistent running of the bearing on which the rotor spins. The sleeve bearing and the […]
