Description

The EPC9131 demonstration board is a 19 V output, 300 kHz single-ended primary-inductor converter (SEPIC) with a 27 W maximum output power and 14 V to 48 V input voltage range. The demonstration board features the EPC2112 enhancement mode (eGaN®) integrated circuit (IC), as well as the LM3481 controller intended for use with MOSFETs. The EPC9131 board contains the complete power stage (including eGaN IC, driver, inductors and input/output capacitors) in a compact 25 mm x 33 mm layout to showcase the performance that can be achieved using the eGaN IC. It also contains a closed-loop SEPIC with optimized control loop. The total board dimension is 48 mm x 50 mm. There are also various probe points to facilitate efficiency measurement. A complete power schematic block diagram of the circuit is given in figure 1. For more information on the EPC2112 eGaN IC or LM3481 controller, please refer to the datasheet available from EPC at www.epc-co.com and www.ti.com respectively. These datasheets should be read in conjunction with this quick start guide.
