Efficient Power Conversion (EPC) expands its family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions with two new devices rated at 100 V and 200 V to address a multitude of critical spaceborne and other high-reliability .

EL SEGUNDO, Calif.— April 2023 — EPC announces the introduction of two new radiation-hardened GaN FETs. The EPC7020 is a 200 V, 11 mΩ, 170 A_Pulsed, rad-hard GaN FET in a small 12 mm² footprint. The EPC7003 is a 100 V, 30 mΩ, 42 A_Pulsed, rad-hard GaN FET in a tiny 1.87 mm² footprint.  Both devices have a total dose radiation rating greater than 1,000K Rad(Si) and SEE immunity for LET of 83.7 MeV/mg/cm² with V_DS up to 100% of rated breakdown. These new devices, along with the rest of the Rad Hard family, EPC7019, EPC7014, EPC7004, EPC7018, EPC7007, 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.

EL SEGUNDO, Calif.— March 2023 — EPC announces the introduction of two new 100 V power stage ICs rated at 15 A (EPC23104) and 25 A (EPC23103). The two devices join the 100 V 35 A power stage IC EPC23102 offered by EPC.

With Electronic Power Steering (EPS), the hydraulic system is replaced with an electric motor that aids the driver only when needed. Its digital assistance control can be modified online to adapt to driving conditions. There are, however, several design constraints to consider. One is that the driver does not want to lack the haptic feedback from the tires, especially when a vehicle is large, such as a truck. Other constraints are determined by safety regulations, particularly for automatic guided vehicles. These constraints require adopting an efficient, accurate and redundant system. Gallium nitride technology helps the designers in all these areas.

EL SEGUNDO, Calif.—  March 2023 – Efficient Power Conversion (EPC), the world’s leader in enhancement-mode gallium nitride FETs and ICs, has teamed up with SHARGE Technology (SHARGE) to design a 67 W USB PD charger with a power display screen. The Retro 67 fast charger uses EPC’s 100 V GaN FET, EPC2218, which can deliver 231 A pulsed current in a tiny footprint of 3.5 mm x 1.95 mm offering designers a significantly smaller, more efficient device than silicon MOSFET for USB PD fast chargers.

EPC2218 provides SHARGE’s All-GaN fast charger with higher efficiency, state-of-the-art power density and lower system cost.

Since the launch of GaN-on-Si enhancement mode power transistors in March 2010 there has been a slow but monotonic shift towards adoption and replacement of silicon-based power MOSFETs. Initial adoption came from risk-taker visionaries in applications such as lidar, high-end audio amplifiers, robots, vehicle headlamps, and high-performance DC-DC converters. For the expansion of GaN for power conversion to get beyond the early adopters, a more user-friendly format than the WLCP needed to be developed. This format, however, needed to preserve the key attributes of small size, low RDS(on), high speed, excellent thermal conductivity, and low cost. In other words, the best package would be the least amount of package technically possible. Enter the PQFN…
