GaN Power Modules Deliver Over 1400 W/in3 for 48V to 12V PoLs

Efficient Power Conversion Corporation (EPC) introduces two new GaN power modules for dc-dc conversion, increasing efficiency across the 48 V to point-of-load (PoL) power architecture. The EPC9205 (pictured above) is a high-power density PCB-based power module for 48V to 12V conversions while the EPC9204 address the 20V to point-of-load conversion with an ultra-thin profile PCB-based power module.

The EPC9205 is an 80V, 10A PCB-based power module featuring the 100V EPC2045 eGaN FET for “plug and play” evaluation of the high performance gained with GaN power transistors. The EPC9205 exceeds 1400 W/in3 per cubic inch in a 48V to 12V application, and occupies less than one-tenth of a cubic inch.

Applications benefiting from the performance of the EPC9205 include the high-performance servers needed for demanding computing applications such as multi-user gaming systems, autonomous cars, artificial intelligence, and cryptocurrency mining.

The EPC9204 is a 20V, 10A PCB-based power module featuring the 30V EPC2111 eGaN® IC capable of operating up to 10MHz. This high frequency capability of the GaN solution reduces the size of the passive components resulting in an ultra-low profile of just 1.2mm from PCB board.

Applications benefiting from the performance of the EPC9204 include point-of-load power conversion for servers, thin form factor mobile devices, and USB-C.

According to Alex Lidow, CEO and co-founder, “As expectations for increasingly power-hungry applications expand while the conflicting desire for equipment to be small and lightweight persists, reducing size and decreasing power consumption is critical. The efficiencies achieved by the EPC9204 and EPC9205 small form factors show how GaN-based power devices, available now, are driving the next generation of computing.”

Quick Start Guides, containing set up procedures, circuit diagrams, performance curves, and bills of material are included with the EPC9204 and EPC9205 for reference and ease of use is provided on-line.

EPC9204 and EPC9205 development boards are priced at $131.25 each and are available for immediate delivery from Digi-Key
