The bq25570 evaluation module (EVM) is a complete module for evaluating the bq25570 energy harvesting charger for storage elements like single-cell Li-Ion/Polymer batteries or super-capacitors. Intended to be powered by high impedance supplies, such as solar panels, thermo-electric generators (TEGs) or piezoelectric generators, the bq25570 regulates its input voltage so that it will not collapse its input source while charging the storage element up to a set voltage point. A power good output indicates when the charger’s storage element reaches a user set voltage level. The bq25570 has an integrated buck regulator that provides a regulated output from the charger output. With minimum changes, the EVM can also be configured as an ultra-low power boost converter, regulating the output voltage from a low impedance source, while simultaneously providing a second output voltage from the buck regulator.
