El Segundo, California: The EPC9101 buck power conversion demonstration circuit board from Efficient Power Conversion (EPC) boasts an 8- to 19-V input to 1.2 V, 18-A maximum output current, and 1-MHz buck converter (see the figure).
The board uses the EPC2014 and EPC2015 enhancement-mode gallium-nitride (eGaN) FETs in conjunction with the LM5113 100-V half-bridge gate driver from Texas Instruments. The LM5113 is the industry’s first driver designed specifically for eGaN FETs. The EPC9101 demonstrates the reduced size and performance capabilities of high-switching-frequency eGaN FETs when coupled with this dedicated eGaN driver.
The power stage footprint of the EPC9101 is 8 by 16 mm and about 8 mm high considering components from both sides. It has a peak power efficiency of 88% and can deliver 18 A of current at 1.2 V. To assist design engineers, the EPC9101 is easy to set up to evaluate the performance of the EPC2014 and EPC2015 eGaN FETs and LM5113 gate driver.
