The 10AEM13920J0000 from e-peas is a Regulated Buck Output Power Management IC that is designed to extract DC power from a harvesting source to store energy in a rechargeable battery and power an application circuit. It requires an input voltage of 2.25 V. This power management IC (PMIC) benefits from a cold-start circuit by which it can start operating with an input voltage as low as 275 mV and a minimum power of 5 µW. This PMIC provides selectable output voltage levels up to 2.8 V, and an output current of up to 135 mA. It extends the battery lifetime by eliminating the primary energy storage in a large range of applications. This PMIC implements constant voltage regulation of the source, allowing for harvesting the maximum power available from the source to charge the storage element. It consists of predefined protection conditions to avoid over-charging or over-discharging of the energy storage element. This is available in a surface-mount package that measures 5 x 5 mm and is ideal for asset tracking, indoor sensors and remote-control applications.
