The embedded MPPT algorithm in these DC-DC converters maximizes the power generated by photovoltaic panels independently of temperature and the amount of solar irradiation.
The SPV1020 is an interleaved DC-DC boost converter operating in the voltage range from 6.5 V to 40 V. It embeds power MOSFETs for active switches and synchronous rectification, minimizing the number of external devices. The 4-phase interleaved topology also avoids the use of electrolytic capacitors, which would limit the lifetime.
The SPV1040 is a monolithic step-up converter with embedded MPPT algorithm that operates over a 0.3 V to 5.5 V input voltage range and maximizes the energy transfer to the load thanks to the very high efficiency. The very low start-up input voltage allows the device to be supplied by even just a few photovoltaic cells or fuel cells, and hence makes it suitable for portable applications.
