This article presents a two-phase DC/DC GaN converter with 120 VDC input operating at 6.7 MHz. 120 VDC is a standard voltage level in the secondary power system at the International Space Station (ISS). Using GaN FET’s high power density and ultra-fast switching, Tell-i’s newly developed SDK board uses two phases to exceed normal switching speeds. Supporting a standard 120-V bus voltage, as used in systems like the ISS, the multi-phase configuration allows interleaving converters to achieve effective switching at 3 MHz, 5 MHz, and an outstanding 6.87 MHz. Optimal and compact layout is achieved with the use of four EPC2019 GaN transistors and two LMG1210 gate drivers for small gate drive and power loops.

Efficient Power Conversion (EPC) expands its family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions in critical spaceborne and other high reliability environments with a device that has the lowest on-resistance of any rad hard transistor currently available on the market.

EL SEGUNDO, Calif.— March 2021 — EPC announces the introduction of the EPC7019 radiation-hardened eGaN FET. The EPC7019, a 40 V, 1.5 mΩ, 530 A_Pulsed, rad-hard eGaN FET in a small 13.9 mm² footprint. The EPC7019 has a total dose rating greater than 1 Mrad and SEE immunity for LET of 85 MeV/(mg/cm²). These devices are offered in a chip-scale package, the same as the commercial eGaN FET and IC family.  Packaged versions will be available from EPC Space.

EPC and Analog Devices introduce reference design using a new Analog controller fully optimized to drive EPC GaN FETs. The combination of the new Analog LTC7890 synchronous GaN buck controller with ultra-efficient eGaN^® FETs from EPC (Efficient Power Conversion) enables up to 2 MHz switching frequency for high power density and low-cost DC-DC Conversion.

EL SEGUNDO, Calif.—  March, 2022 — EPC announces the availability of the EPC9160, a dual output synchronous buck converter reference design board operating at 2 MHz switching frequency that converts an input voltage of 9 V to 24 V to a 3.3 V or 5 V output voltage and delivers up to 15 A continuous current for both outputs. Thanks to the high switching frequency the converter size is very small, only 23 mm x 22 mm for both outputs, and the inductor height is only 3 mm.

Automotive 48 V/12 V converters are essential in modern hybrid electric vehicles, as the energy is exchanged between the 48 V and 12 V buses. This two-voltage system accommodates legacy 12 V systems and provides higher power for 48V to loads such as vacuum and water pumps, electric super chargers, steering, and audio systems. Among all the requirements for the 48 V/12 V converter, efficiency, power density, size and cost are on the top of the list. This article addresses these design criteria by employing the GaN ePower™ Stage, EPC23101, and compares it with a previous design using discrete EPC2206 devices.

In this article, the most common reasons for some customers to be slower in their embracing what is clearly a displacement technology for their older silicon-based power MOSFETs will be discussed. Without going into the detailed statistics, a list of reasons, in order of frequency is derived. This list is based upon the understanding that some applications will place higher emphasis than others on certain characteristics of GaN. Our discussion is limited to devices rated at less than 400 V, as that is the application focus for Efficient Power Conversion (EPC) FET and IC products.

A few simple thermal management guidelines can help conduct heat away from GaN FETs. Enhancement-mode gallium nitride (eGaN) FETs offer high power-density with ultra-fast switching and low on-resistance, all in a compact form factor. However, the power levels these high-performance devices provide can be limited by extreme heat-flux densities. If not managed properly, the generated heat can compromise reliability and performance. Fortunately, chip-scale packaging for eGaN FETs can be leveraged at the board-side and the backside (i.e., case) to better dissipate heat.
