This data brief introduces the features of the STEVAL-ISV008V1 300 W PV converter demonstration board based on the SPV1020, including a PWM mode DC-DC boost converter, MPPT algorithm controlled duty cycle, 0-40 V operating voltage range, overvoltage, overcurrent, overtemperature protections, soft-start, up to 98% efficiency, automatic transition to burst mode for improved efficiency at low solar radiation, SPI interface, RoHS compliant, etc.
The STEVAL-ISV008V1 is a demonstration board designed to be integrated into photovoltaic panels based on the SPV1020. It contains three SPV1020 monolithic DC-DC boost converters on the same PCB, suitable for distributed PV panels with three isolated strings. The board allows the outputs of the SPV1020s to be connected in parallel, which is the default setting and the only allowed configuration for this specific model.
