WIRELESS POWER RECEIVER WITH PROGRAMMABLE POWER PATH |
摘要 |
A wireless power receiver IC in which the power path can be reconfigured as either a low-dropout regulator (LDO), a switched-mode power supply (SMPS) or a power switch (PSW) is provided. All three modes share the same pass device to reduce die area and share the same output terminal to reduce pin. In an inductive wireless receiver, the power path can be reprogrammed on the fly to LDO or PSW mode or can be reprogrammed on the fly to SMPS or PSW mode. In a resonant or multi-mode wireless receiver, the power path can be reprogrammed on the fly to SMPS or PSW mode. Furthermore, to achieve high power transfer efficiency performance, using N-channel MOSFET as its pass device has better efficiency and smaller die area than P-channel MOSFET pass device. |
