EPC shrinks eGaN FET – EPC2069 suits high power density performance
For high power density telecoms and computing, the EPC2069 eGaN FET is the latest 40V, 1.6mOhm enhancement-mode GaN on silicon (eGaN) power FET from Efficient Power Conversion (EPC).
According to EPC, it offers designers a device that is smaller, more efficient, and more reliable than currently available devices for high performance, space-constrained applications.
The EPC2069 can be used for applications with demanding requirements for high power density performance including 48 to 54V input servers. Lower gate charges and zero reverse recovery losses enable high frequency operation of 1.0MHz and above, at high efficiency. The EPC2069 has a footprint of just 10.6mm2. The eGaN FET can support 48 to 12V DC/DC from 500W to 2kW and exceed 98 per cent efficiency. The use of eGaN devices in both the primary side and the secondary side is required to achieve maximum power density of less than 4000W/in3.
Alex Lidow, EPC’s co-founder and CEO, comments: “The EPC2069 is… designed for the secondary side of the LLC DC/DC converter from 40 to 60V to 12V, which is becoming very common for the new 48 to 54V input servers required for high density computing applications such as AI and gaming. This 40Vt device offers both smaller size and reduced parasitics compared with previous generation 40V GaN FETs and at lower cost”.
An accompanying EPC90139 development board is a 40V maximum, 40A maximum output, half bridge with onboard gate drives and featuring EPC2069 eGaN FETs. The 2.0 x 2.0-inch (50.8 x 50.8mm) board is designed for optimal switching and contains all critical components to evaluate the EPC2069.
Both the EPC2069 and EPC90139 are available to order and for immediate delivery from Digi-Key.
EPC specialises in enhancement-mode gallium nitride (eGaN)-based power management. eGaN FETs and ICs provide performance many times greater than the best silicon power MOSFETs in applications such as DC/DC converters, remote sensing technology (lidar), motor drives for e-mobility, robotics, and drones, and low cost satellites, says EPC.
