New Products

Ruggedized 100V HEMT Adds to e2v HiRel’s GaN Power HEMT Family – This new product, TDG100E90, joins the recently announced 650V, 60A TDG650E60, and is available to provide a lower step-down voltage in high-reliability power circuitry. Compared to Silicon MOSFET devices, the GaN-based TDG100E90 HEMT significantly reduces losses and EMI, due to no reverse recovery characteristics. To reduce drain-source on-resistance (RDS(on)) or increase the load current, the TDG100E90 can easily support parallel driving configuration. The use of high-performance GaNPX® packaging allows very high-frequency switching, extremely low inductance, and excellent thermal characteristics, enabling customers to significantly reduce the size and weight of power electronics.

Ruggedized, High Reliability 650V GaN Power HEMT – The new TDG650E60 is the highest voltage GaN power device available on the market for space and military applications. It is now available with both top- or bottom-side cooled options. It delivers the efficiency, size, and power density-benefits required in those critical high-rel applications. The TDG650E60 boasts an extremely small form factor and leverages the patented Island Technology® from GaN Systems. It is a scalable, vertical charge dissipating system that gives the power transistor ultra-low thermal losses, high power density, no-charge storage, and very high switching speeds, and has been tested and qualified under the industry’s most stringent testing regimen.

Peregrine’s power management products follow a steep tradition of high performance and efficiency. The flagship power management family supports DC to DC conversion with radiation-tolerant point-of-load (POL) synchronous buck regulators with integrated switches. These devices offer SEE immunity to a linear energy transfer (LET) greater than 90 MeV.cm2/mg and TID of 100 kRad(Si). By offering superior performance, smaller size and reduced weight, these power management products can replace multi-chip modules in sensitive space applications.

DC-DC converters from Peregrine are the industry’s smallest, space-grade, monolithic non-isolated distributed power solutions. They can replace traditional multi-chip modules that power field-programmable gate array (FPGA), digital signal processor (DSP), ASIC and SRAM power management designs. The combination of small size, high levels of integration and efficiency lowers total system weight and associated costs. Peregrine’s converters are designed to operate from a wide bus rail and provide an output voltage supply rails for analog, digital and RF payloads while delivering continuous output current. The converters also achieve high peak efficiency of 93+ percent through monolithic integration that reduces switch loss. The components feature an external resistor that provides adjustable slope compensation to optimize closed-loop bandwidth across output voltage and switching frequency range.

Peregrine’s DC-DC converters are radiation-hardened and immune from single event latch-ups (SELs), making them ideal for space applications. They are also optimized for defense and commercial applications, such as satellite systems, military radios, radar, engine control modules (ECMs), down-hole drilling and other high-reliability systems.
