EPC Introduces a 12 V ? 48 V 500 W GaN Boost Converter Demonstration with Same BOM Size as Silicon, Offering Superior Efficiency and Power Density
EPC announces the availability of the EPC9166, a 500 W DC-DC demo board that converts a 12 V input to 48 V output. The EPC9166 demo board demonstrates the Renesas ISL81807 80 V two-phase synchronous boost controller with the latest generation EPC2218 eGaN FETs from EPC to achieve greater than 96.5% efficiency in a 12 V input to 48 V regulated output conversion with 500 kHz switching frequency. The output voltage can be configured to 36 V, 48 V, and 60 V. The board can deliver 480 W power without a heatsink.
Regulated DC-DC boost converters are widely used in data center, computing, and automotive applications, converting a nominal 12 V to a 48 V distribution bus among other output voltages. The main trend has been towards higher power density.
eGaN® FETs provide the fast switching, high efficiency and small size that can meet the stringent power density requirements of these leading-edge applications. EPC2218 is the smallest and highest efficiency 100 V FET in the market. The ISL81807 is the industry's first 80 V dual-output/two-phase (single output) synchronous buck controller with integrated GaN driver, supporting frequencies up to 2 MHz. The ISL81807 uses current mode control and generates two independent outputs or one output with two interleaved phases. It supports current sharing, synchronization for paralleling more controllers/more phases, enhanced light load efficiency and low shutdown current. ISL81807 directly drives EPC GaN FETs, ensuring easy design, low component count and solution cost.
Alex Lidow, CEO of EPC, commented, "The Renesas controller IC makes using GaN even easier. We are delighted to work with Renesas to combine the benefits of their advanced controllers with the performance of GaN to provide customers with a low component count solution that increases efficiency, increases power density, and reduces system cost."
"The Renesas ISL81807 is designed to fully exploit the high performance of GaN FETs for high power density solutions," said Andrew Cowell, Vice President of the Mobility, Industrial and Infrastructure Power Division at Renesas. "ISL81807 reduces BOM cost for GaN solutions because it does not require an MCU, current sense op amp, external driver or bias power. It is also fully protected and integrates the GaN drivers. With the ISL81807, designing with GaN FETs is as simple as designing with silicon-based FETs."
