Efficient power conversion with HSC converters & source-down MOSFETs
As data centers and generative AI systems demand more computing power and energy, the search for efficiency improvements in the power conversion process has become more crucial. The introduction of the 48 V power delivery (PD) architecture represents a first breakthrough in power conversion, and further advancement is represented by the hybrid switched capacitor converter topology, which, combined with source-down technology, takes power density and efficiency to the next level.
Key benefits:
HSC offers higher efficiency regardless of the component variation
HSC offers lower RMS at both synchronous rectifier and magnetic level compared to the classic LLC
Source-down package technology offer
30% lower RDS, decreasing I²R losses
Lower package-related parasitics, reducing the FOM and leading to lower switching losses
Lower RthJC, optimizing the distribution of the generated heat from the package
Optimized layouts where the large GND area can be utilized as a heatsink, this since the thermal pad is located on the source pin
