Introduction of High-Capacitance 100V MLCC in Line with the Expansion of 48V Power Systems for AI Servers
▷ With the increase of power consumption of AI servers, a resulting trend is the adoption of more 48V Power Systems with better efficiency. The 48V Power System enables the delivery of higher power with the same current.
▷ The 48V System in AI server circuits is generally applied in two key areas:
1. The 48V output circuit of the Server PSU (AC/DC).
2. The 48V input circuit of the Power Module mounted on the server board. [Figure 1]
▷ From a design perspective, when applying high-capacitance 100V MLCC to 48V input/output voltage circuits, the usage of Soft Termination to reduce mechanical stress is considered, as well as the evaluation of the Self-temperature Rise of the MLCC caused by high ripple currents. [Figure 2/3]
