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.

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.
