title = "Chiplet-LEGO: Delivering Multiple Voltage Rails to Chiplets with Chiplet VRMs",
abstract = "This paper presents Chiplet-LEGO, a single-input multiple-output (SIMO) linear extendable group operated (LEGO) voltage regulator module (VRM) architecture as a new development of the LEGO-VRM family. This architecture not only offers a high voltage conversion ratio but also delivers multiple individually regulated output voltages, making it well-suited for VRMs in system-on-chip (SoC) applications with multiple voltage rails. The Chiplet-LEGO is well suited to numerous numbers of independently regulated output voltages with scalable power capability. Dynamic models were derived to understand the cross-regulation behaviors. A 24 V-to-1 V 120 W dual-output Chiplet-LEGO prototype with discrete components was built and tested to evaluate the effectiveness of the analysis.",
