This datasheet provides detailed information about the SPV1020, a 4-phase interleaved DC-DC boost converter designed to maximize the power generated by photovoltaic panels regardless of temperature and solar radiation amount.
The SPV1020 is a monolithic 4-phase interleaved DC-DC boost converter designed to maximize power generated by photovoltaic panels. It features a built-in MPPT algorithm with 0.2% accuracy and operates with an input voltage range of 6.5V to 40V. The device integrates power MOSFETs for active switches and synchronous rectifiers, eliminating the need for external electrolytic capacitors.
| Operating input voltage | 6.5 - 40 V |
|---|---|
| Operating output voltage | 40 V |
| Operating output current | 9 A |
| LX switch current limit | 4.5 A |
| PWM frequency (default) | 100 kHz |
| Power capability | 320 W |
| Efficiency | Up to 98% |
| MPPT accuracy | 0.2% |
| Thermal shutdown threshold | 150 °C |
The switching frequency is internally generated and set by default at 100 kHz, but is externally adjustable from 50 kHz to 200 kHz.
No, the 4-phase interleaved topology obviates the need to use electrolytic capacitors.
The embedded logic performs the MPPT algorithm on the PV cells to maximize power generation independent of temperature and solar radiation.
