Description
The AP4473 is an ultra-low consumption power management chip that integrated a step-up DC-DC converter and hysteresis comparators. The AP4473 requires only 15mV (typical) input to start boosting using an external transformer. The AP4473 has hysteresis operation switch that can control the power supply for the external system (sensors, wireless modules, LEDs) while protecting external storage (capacitors), and the external system. The AP4473 is ideally suited for energy harvesting. This provides a self-powered wireless sensor node with simple hardware design.
Key Features
Energy harvesting A technology that extracts minute energy and converts it into electric power.
Suppressing current consumed by self The biggest feature is that it consumes the smallest current
Applications
■Energy Harvesting ・Wireless Sensor Node ・Wearable and Portable Device ■Example of Energy Harvester (several mW to several mW sources) ・Thermal
