摘要：

A power interface IC is designed and demonstrated to convert and manage power for a wireless tire pressure sensor node. Power conversion is performed using on-chip switched-capacitor converters with size-optimized devices and level-shifting gate drivers. A synchronous rectifier efficiently harvests energy from an electromagnetic shaker and control circuitry regulates the output voltage while minimizing power consumption. The converters achieve efficiencies approaching 80%.
