      Low Power Design For IoT


      Power Management Unit (PMU) for IoT


      General Description

      Power-consumption will affect the IoT’s functionality, and power management has become one of the most important and differentiating feature in the low power application such as wearable. Many devices have multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power to charge their batteries including USB. Brite's Power Management Unit (PMU) provides high efficiency power conversion that minimizes energy loss, and is used in battery-powered devices, smart appliances, healthcare, home automation, consumer electronics, industrial automation.
