Description

The STEVAL-ISV004V2 demonstration board is

based on the SPV1020 monolithic DC-DC boost

converter in a PSSO36 package designed to

maximize the power generated by photovoltaic

panels, independent of temperature and amount

of solar radiation.

Optimization of power conversion is obtained

through embedded logic, which performs the

MPPT (max power point tracking) algorithm

based on monitoring of the voltage and current

supplied by the PV cells.

The precision of the algorithm is guaranteed by a

10-bit ADC for current and voltage sensing.

For cost-effectiveness and miniaturization of the

application, the SPV1020 embeds 8 power

MOSFETs for active switching and synchronous

rectification, minimizing the number of external

components required. The 4-phase interleaved

topology of the DC-DC converter means that

electrolytic capacitors can be avoided, which

would otherwise severely limit system lifetime.

Doc ID 17824 Rev 1

PWM switching (duty cycle varies between 5%

and 90%, with 0.2% accuracy) is regulated by

default at 100 kHz by an internal oscillator, but is

programmable between 50 kHz and 200 kHz via

an external resistor.

Application safety is ensured by stopping the

PWM switching in case of output overvoltage (set

by external trimming), overcurrent (internally

regulated at 4 A for each channel) and over-

temperature (160
