BQ25570 Boost Power Converter Energy Collector Module Solar Energy Collector Converter Boost Charging Buck Conversion Low Power Wireless Network Voltage Converter

The BQ25570 device is specifically designed to efficiently extract microwatts (W) to milliwatts (mW) of power generated from a variety of high output impedance DC sources like photovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources. The battery management features ensure that a rechargeable battery is not overcharged by this extracted power, with voltage boosted, or depleted beyond safe limits by a system load. In addition to the highly efficient boosting charger, the bq25570 integrates a highly efficient, nano-power buck converter for providing a second power rail to systems such as wireless sensor networks (WSN) which have stringent power and operational demands.
