EPC2304

Overview

The EPC2304 is a GaN FET rated for 200 V with an on-resistance of 5 mΩ in a 7QFN package. It serves as the primary switching component in the PFC stage of the EPC91107KIT reference solution, which forms part of a modular 5 kW AC to 48 V/50 V power system. This configuration supports ORv3-class server and AI power systems by boosting 200 V AC to 400 V DC.

Feature Summary

• Enables high-efficiency power conversion within 4-level totem-pole PFC topologies
• Supports compact and modular power supply architectures for dense server applications
• Facilitates balanced thermal distribution in multi-module isolation stages

Applications

• ORv3 48 V server PSUs
• AI server racks
• Modular scalable rack power systems
• High-density AC/DC front ends with isolated 48 V/50 V bus

Procurement Notes

Verify the specific package variant and voltage rating against the target design requirements. Confirm compatibility with the intended PFC topology, specifically the 4-level totem-pole configuration used in the EPC91107KIT reference design. Ensure thermal management solutions align with the device's power dissipation characteristics in high-frequency switching environments.

Selection Notes

Select this component for designs requiring low on-resistance and high voltage tolerance in AC-DC conversion stages. It is optimized for integration into modular power architectures that demand high efficiency and power density. Consider its performance in conjunction with complementary LLC devices for complete isolation stages.

Part Context

This device is a key element in EPC's modular 5 kW reference solution, paired with the EPC2305 in the LLC stage. Together, they enable a complete AC to 48 V/50 V path designed for next-generation computing infrastructure, emphasizing scalability and thermal balance.
