EPC launches 200V, 25mΩ GaN power transistor 12 times smaller than equivalent MOSFETs
Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA – which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) for power management applications and ICs – has launched the EPC2046 power transistor – which has a voltage rating of 200V and maximum RDS(on) of 25mΩ with a 55A pulsed output current – for applications including wireless power, multi-level AC-DC power supplies, robotics, solar micro inverters, and low-inductance motor drives.
The chip-scale packaging of the EPC2046 handles thermal conditions far better than plastic-packaged MOSFETs since the heat is dissipated directly to the environment with chip-scale devices whereas the heat from the MOSFET die is held within a plastic package, says EPC. The new device measures just 0.95mm x 2.76mm (2.62mm2), so designers no longer have to choose between size and performance, notes the firm.
“Manufactured using our latest fifth-generation process, the EPC2046 demonstrates how EPC and gallium nitride transistor technology is increasing the performance and reducing the cost of eGaN devices,” says co-founder & CEO Alex Lidow. “This opens up entirely new applications beyond the reach of the aging silicon MOSFET and offers a big incentive for users of MOSFETs in existing applications to switch,” he adds. “This latest product is further evidence that the performance and cost gap of eGaN technology with MOSFET technology continues to widen.”
The EPC9079 development board is a 200V maximum-device-voltage half-bridge with onboard gate driver, featuring the EPC2046, onboard gate drive supply and bypass capacitors. This 2” x 1.5” board has been laid out for optimal switching performance and contains all critical components for easy evaluation of the 200V EPC2046 eGaN FET.
The EPC2046 eGaN FETs are priced at $3.51 each in 1000-unit quantities. The EPC9079 development boards are priced at $118.75 each. Both are available for immediate delivery from distributor Digi-Key.
