摘要

This paper describes a dual-output, reconfigurable integrated power management (IPM) ASIC for inductive power delivery. The proposed ASIC operates either as a current-mode (CM) rectifier or a boost converter by sharing the receiver (Rx) coil (L_{Rx}) to improve performance of inductive power transmission against the variations of Rx input power (P_{Rx}) and dual-output DC power (P_{L}+ P_{Hv}). Conventional IPM structures either fail to generate regulated outputs (e.g., V_{L} and V_{Hv}) when the required P_{L}+ P_{Hv} exceeds P_{Rx} or suffer from low power-conversion efficiency (PCE) when P_{Rx} exceeds P_{L}+ P_{Hv} due to voltage regulation and protection. To overcome these challenges, the proposed ASIC offers the unique capabilities of 1) generating multiple regulated outputs (V_{L}= ext{2.6},ext{V},,V_{Hv}= ext{3.9},ext{V}) directly from L_{Rx} with single-stage conversion, 2) efficient CM operation with active rectification, enabled by adaptive switching control (ASC), 3) charging a large capacitor (C_{S}) with the purpose of operating as a shared-inductor boost converter (SBC), transferring energy from C_{S} to C_{L} and C_{Hv}, when P_{Rx}< P_{L}+ P_{Hv}, and 4) efficient voltage-power regulation (VPR). A proof-of-concept chip was fabricated in a 0.35-m 2P4M standard CMOS process occupying 1.35-mm(2) active area. In measurements, the proposed ASIC was able to successfully provide regulated V_{L}= ext{2.6},ext{V} and V_{Hv}= ext{3.9},ext{V} despite significant variations in P_{Rx}, P_{L}, and P_{Hv}. Moreover, the chip extended the peak output power range by 750 and improved the PCE by 1.3 times and 8.1 times thanks to the ASC and VPR, respectively.
