Abstract
There is a growing demand for efficient IC-level power conversion from highvoltage (HV) >200V down to below 5V. Applications include decentralized IoT and smart home, supplied from the grid, as well as control circuits in e-cars with DC-link supply voltages on the order of 400V. While energy harvesting is limited to power levels <1mW, the grid as well as HV batteries provide much higher power, readily available in buildings, etc. However, conventional voltage conversion is achieved by expensive and large power modules [1]-[5], which show poor efficiency below 500mW. Hence, they are not well suitable to supply microcontrollers, sensors, etc. The presented converter IC closes the power gap between energy harvesting and power modules (Fig. 11.3.1), converting voltages of V in=100 to 325V into a low-voltage output V out=3.3 to 10V.
