EL SEGUNDO, Calif. -- June 20, 2013

Efficient Power Conversion Corporation (EPC) introduces the EPC9107, a fully
functional buck power conversion demonstration circuit. This board is a 9 V-28
V input to 3.3 V, 15 A maximum output current, 1MHz buck converter. It uses
the EPC2015 eGaN FET in conjunction with the LM5113 100V half-bridge gate
driver from Texas Instruments. The EPC9107 demonstrates the reduced size and
performance capabilities of high switching frequency eGaN FETs when coupled
with this dedicated eGaN driver.

The EPC9107 demonstration board is 3” square and contains a fully closed-loop
buck converter with optimized control loop. The complete power stage including
eGaN FETs, driver, inductor and input/output caps is in an ultra compact 0.5”
x 0.5” layout to showcase the performance that can be achieved using the eGaN
FETs with the LM5113 eGaN driver.

Despite its small size, the board has peak power efficiency greater than 96%
and is capable of delivering 15 amps of current at 3.3 volts. To assist the
design engineer, the EPC9107 demonstration board is easy to set up and
contains various probe points to facilitate simple waveform measurement and
efficiency calculation.

About EPC

EPC is the leader in enhancement mode gallium nitride based power management
devices. EPC was the first to introduce enhancement-mode
gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in
applications such as servers, wireless power transmission, envelope tracking,
RF transmission, power-over-ethernet (PoE), solar micro inverters, energy
efficient lighting, and class-D audio amplifiers with device performance many
times greater than the best silicon power MOSFETs.
