ISSCC 2024 Session 28 Overview: High-Density Power Management

As compute density rises to meet the demands of growing cloud and AI workloads, power delivery emerges as a critical performance bottleneck due to increasing power demands.Consequently, there is a high demand for improving power density.This session showcases notable achievements in achieving high power density, including a low-dropout regulator (LDO) with reduced on-chip capacitance while maintaining high power-supply rejection (PSR), innovative topologies interfacing high input voltages and large conversion ratios that enhance efficiency with smaller inductors, optimized switched-capacitor (SC) topology arrangements for maximum efficiency, and a 200A voltage regulator chiplet addressing both system-and circuit-level techniques.
