At APEC 2024, Power Integrations‘ chairman and CEO, Balu Balakrishnan, “declared war on DC-DC post regulators”, as the company introduced the GaN-based InnoMux-2 switcher IC family. The company said that the new ICs are an example of its value and energy focus because it combines AC-DC and DC-DC stages into a single power converter, resulting in a reduction in power ...
Analog Devices has created a stand-alone 100V half-bridge driver for GaN power hemts “with a propagation delay of 10ns and delay matching of 1.5ns between the top and bottom channels, making it suitable for high-frequency dc-dc converters, motor drivers and class-D audio amplifiers”, according to the company. Called LT8418, this IC looks very much like the output stage used within ...
Despite there potential efficiency, piezoelectric power converters are a technology that has never become popular, even though the power transfer component is thin and flat, instead of boxy like an inductor, and piezoelectrics are quick and simple to make – much like a ceramic capacitor. The flip-side are the disadvantages, warranting a mushrooming component count to temper them. Enter the ...
Diodes is aiming at active matrix OLED panels with three-output power management dc-dc converter. Running from 2.9 to 4.8V, AL3565 produces: 4.6 to 5.0V (VPOS) with 0.5% accuracy at up to 500mA from a buck-boost converter -1.4 to -5.4V (VNEG) with 0.5% accuracy at up to 500mA from an inverting buck-boost converter 5.8 to 7.9V (AVDD) with 0.5% accuracy at ...
Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...
E-peas has created an energy harvesting IC specifically for hand-held remote controls and wireless keyboards equipped with small solar cells. A cold start is possible from an input voltage as low as 275mV if 5µW of power is available. There are two versions, which optimise loading of the photovoltaic source in two different ways to get the best out of ...
Texas Instruments has announced a series of GaN power switches for ac-dc and dc-dc converters that include an integrated driver, protection and current sense emulation. The parts, called LMG362x, differ in the size of the GaN hemt switch included. They are: LMG3622 650V120mΩ 8.5A LMG3624 650V 170mΩ 6A LMG3626 650V 270mΩ 3.6A “Using the LMG3622 only requires setting the desired ...
Vox Power has announced a set of conduction-cooled 300W dc-dc converters, for railway and other rugged environment use. Measuring 188.6 x 116 x 25.4, the 33.6 to 160V input range is intended to cover 48, 72, 96 and 110 V railway batteries. Dips to 28.8V can be ridden through covered for 100ms, complete drop-outs for 10ms, and 168V peaks for 1s. ...
Recom has built an isolated 5V output dc-dc converter that will work from 9 – 36Vdc. Measuring ~32 x 21 x 10mm, the through-hole pin-out of REC5K-2405SRW/H4/A is based on the industry-standard DIP24 plastic package. Nominally it is designed to run from 24V, and will deliver its full 1A output from inputs between 18-36Vdc, then 4A from 12-18V, and 3A ...
Vishay has squeezed point-of-load buck regulators into a 10.6 x 6.5 x 3mm package, including one that accepts inputs across 4.5 to 60V and can deliver 6A continuous at voltages down to 800mV. Another has a 25A output. Internal synchronous rectification allows efficiency, in one model, to be as high as 97%. “The regulator modules each offer two high performance ...
