The Infineon 140 W Reference Board for ultra high power density in USB C chargers with EPR and adapters. The reference board was developed for USB PD applications with a wide input range and output voltage from 5 V to 28 V. The nominal output power of this design is 140 W. The board has a dimension of 109.5 mm x 38.5 mm x 24 mm and a power density of 22.67 W/in³. Two layers PCBs are used for the whole system, which results in low system cost. Low no load input standby power performance
Low external BOM cost and count
High power density and high switching frequency
Ease of configurable design and optimization with GUI tools
Pulse skipping for improved light load efficiency
Bus voltage level following output voltage
