An integrated circuit made using GaN-on-Si substrates has been in production for over five years. The ultimate goal is to achieve a single component IC that merely requires a simple digital input from a microcontroller and produces a power output that drives a load efficiently, reliably under all conditions, in the smallest space possible, and economically. Discrete power transistors, whether silicon-based or GaN-on-Si, are entering their final chapter. Integrated GaN-on-Si can offer higher performance in a smaller footprint with significantly reduced engineering required.

Efficient Power Conversion (EPC) introduces the first of a new integrated circuit (IC) product family offering higher performance and smaller solution size for high power density applications including DC-DC conversion, motor drive, and Class-D audio.

EL SEGUNDO, Calif.— March 2020 — EPC announces the introduction of an 80 V, 12.5 A power stage integrated circuit designed for 48 V DC-DC conversion used in high-density computing applications and in motor drives for e-mobility.

This article demonstrates the performance improvements that can be obtained when using GaN FETs in combination with suitable GaN FET drivers in 12-V input to 1-V output point-of-load converters. The example design described here uses the uP1966D, a dual-channel, synchronous driver IC from uPI Semiconductor in combination with an EPC2100 GaN asymmetrical half-bridge FET from Efficient Power Conversion.

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in the ecosystem of power electronics that support GaN-based designs.

The EPC9205 is a high-power density PCB-based power module for 48 V – 12 V conversions while the EPC9204 address the 20 V – point-of-load conversion with an ultra-thin profile PCB-based power module.

This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.

The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within reach for ordinary consumers.

The previous installment in this series focused on the physics of failure surrounding thermo-mechanical reliability of EPC eGaN wafer level chip-scale packages. A fundamental understanding of the potential failure modes under voltage bias is also important. This installment will provide an overview of the physics of failure associated with voltage bias at the gate electrode of gallium nitride (GaN) field effect transistors (FETs). Here we look at the case of taking the gate control voltage to the specified limit and beyond to investigate how eGaN FETs behave over a projected lifetime.

The first three installments in this series covered field reliability experience and stress test qualification of EPC’s enhancement-mode gallium nitride (eGaN) field effect transistors (FETs) and integrated circuits (ICs). Excellent field reliability that was documented is the result of applying stress tests covering the intended operating conditions the devices will experience within applications. Of equal importance is understanding the underlying physics of how eGaN devices will fail when stressed beyond intended operating conditions (e.g. datasheet parameters and safe operating area). This installment will take a deeper dive into the physics of failure centered around thermo-mechanical reliability of eGaN wafer level chip-scale packages (WLCSP).
