Moreover, to withstand high loads, the use of interleaved topologies is important for the increase in required power. When using interleaved topologies, excellent thermal distribution is necessary to balance the MOSFET degradation. This article presented a simple and easy thermal-balancing circuit combined with the MPQ2908A-AEC1, which improves current sharing and temperature distribution in multi-phase designs, and meets standardized EMC requirements, such as CISPR 25 Class 5. The temperature difference between the multi- phase converter phases can be effectively reduced from 2 K to 0.5 K using well- known and commonly used components.
