EPC announces the availability of the EPC9148 and EPC9153 demonstration boards for 48 V DC-DC conversion. The EPC9153 is a 250 W, extremely thin, power module using a simple, low-cost synchronous buck configuration delivering a 98.2% peak efficiency with a maximum component height of 6.5 mm. The EPC9148 utilizes a multilevel topology enabling a maximum component height less than 4 mm, while maintaining a 98% peak efficiency.
Both solutions integrate Microchip Technology’s dsPIC33CK digital signal controller (DSC) with the latest generation 100 volt eGaN FETs from EPC. These solutions achieve greater than 98% efficiency at 12.5 A in an ultra-thin footprint. The flexibility of the Microchip digital controller allows the input voltage of these boards to be adjusted from 44 V – 60 V and the output voltage from 5 V – 20 V (more info).
