Simplify your simulated GaN designs with LTSpice model
Prior to building hardware, power system design engineers want to be fast, accurate and confident with their simulated designs. Achieving these goals with GaN designs has become easier with GaN Systems’ new set of LTSpice models. Increasing efficiency and power density requires proper layout and understanding of the characteristics of these fast transistors.
DC/DC converters for next-gen SiC MOSFETs
The main challenges of driving SiC MOSFETs include high-frequency and high-voltage switching. Extreme voltage potentials between the control and power side can wear down isolation barriers and lead to failures. To meet these tough requirements, RECOM has recently introduced a new 2W DC/DC converter series specially designed to power the latest generation of SiC MOSFETs. Switching SiC MOSFETs requires turn-on and turn-off voltages atypic...

Power limiter delivers reliable, repeatable protection
Availability and full design support capabilities for a power limiter from Peregrine Semiconductor have been announced by Richardson RFPD. The UltraCMOS PE45361 builds on the success of Peregrine's 50-watt UltraCMOS power limiters and adds higher pulsed power handling, a lower limiting threshold and positive threshold control.
Mixer supports DC to 6GHz IF & 0dBm LO Drive
Analog Devices, which recently acquired Linear Technology, has announced the LTC5552, a double balanced mixer that features best-in-class wideband matching from 3GHz to 20GHz. The mixer can be used as an up- or downconverter. The LTC5552 is especially useful in upconversion applications with its DC capable differential IF port that enables the LO to be close in frequency to the RF. Its low LO to RF leakage of less than –25dBm greatly eases ...
DC/DC converters drive capacitive loads up to 2200µF
At only 5.5mm high, the latest RECOM R1SX 1W unregulated DC/DC converters, available now at Dengrove Electronic Components, are 20% slimmer than alternative converters, and are packaged as compact, 12.75mm x 10.8mm, surface-mount, open-frame modules. In addition to satisfying EN 55022/024 and IEC/UL/EN 60950-1, the modules are certified to the incoming IEC/UL/EN 62368-1 safety specification.
How to achieve effective thermal management for EV batteries
With the growing demand for battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV), dissipating battery heat and providing protection against electrical interference have never been more pertinent. According to the ‘European Vehicle Market Statistics Pocketbook 2016/17’, which is published annually by the International Council of Clean Transportation (ICCT), electric vehicles already comprise 1.5% of all new ...
