Product details
Overview
STEVAL-ISV004V2 from STMicroelectronics is a 240 W photovoltaic (PV) demonstration board built around the SPV1020 monolithic DC-DC boost converter in PSSO36 package, implementing MPPT with 0.2% duty cycle accuracy, 100 kHz (programmable 50–200 kHz) PWM switching, and 98% peak efficiency for solar panel power optimization.
For engineers reviewing the STEVAL-ISV004V2 datasheet, STEVAL-ISV004V2 pinout, STEVAL-ISV004V2 application, or STEVAL-ISV004V2 equivalent, this board enables rapid validation of high-efficiency, multi-phase PV energy harvesting systems with integrated overvoltage, overcurrent, and overtemperature protection, SPI-based configuration, and burst-mode operation under low irradiance.
Technical Context
The board implements a 4-phase interleaved synchronous boost topology using eight internal MOSFETs, eliminating electrolytic capacitors to extend lifetime. It integrates a 10-bit ADC for real-time voltage/current sensing to execute the MPPT algorithm with 0.2% duty cycle resolution.
PWM frequency is set by an internal oscillator at 100 kHz (adjustable via external resistor from 50 kHz to 200 kHz), while protection logic halts switching on output overvoltage (externally trimmed), per-channel overcurrent (4 A threshold), or die temperature exceeding 160 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6.5 V to 45 V - supports wide-range PV panel string configurations including partial shading conditions. |
| Max Output Voltage | 40 V - compatible with standard 36 V nominal battery charging and grid-tie inverters. |
| Max Input Current | 8 A - enables full 240 W operation at minimum input voltage (6.5 V × 8 A ≈ 52 W; higher at typical 20–40 V PV operating points). |
| MPPT Accuracy | 0.2% duty cycle resolution - ensures precise tracking of maximum power point under dynamic irradiance and temperature shifts. |
| Peak Efficiency | 98% - achieved via synchronous rectification and interleaved phase cancellation reducing RMS current stress and conduction losses. |
| Switching Frequency | 100 kHz default, programmable 50–200 kHz - balances EMI control, magnetics size, and MOSFET switching loss trade-offs. |
| Protection Functions | OVP (externally adjustable), OCP (4 A/channel), OTP (160 °C) - autonomous shutdown prevents component damage during fault conditions. |

FAQ
What is the primary function of the STEVAL-ISV004V2 evaluation board?
The STEVAL-ISV004V2 is a complete 240 W PV converter demonstration platform that validates the SPV1020 IC's ability to maximize solar panel power extraction using hardware-accelerated MPPT, 4-phase interleaved boost conversion, and integrated protection. It is not a production-ready module but a design verification tool with test points, jumpers, and SPI interface for algorithm tuning and performance benchmarking.
Does the board support real-time MPPT parameter adjustment?
Yes - the board exposes the SPV1020's SPI interface, allowing engineers to read real-time voltage/current ADC data, modify MPPT loop coefficients, adjust switching frequency via external resistor selection, and reconfigure protection thresholds (e.g., OVP trim point) during live operation without hardware changes.
Can the STEVAL-ISV004V2 operate without external microcontroller intervention?
Yes - the SPV1020 executes autonomous MPPT using its embedded digital controller and 10-bit ADCs; no host MCU is required for basic operation. The board includes on-board circuitry for standalone startup, soft-start, burst-mode transition, and fault recovery, making it functional as a self-contained PV optimizer.
Is the STEVAL-ISV004V2 still recommended for new designs?
No - STMicroelectronics has marked STEVAL-ISV004V2 as obsolete (per Doc ID 17824 Rev 3). While functional and supported for legacy system maintenance, new designs should consider ST's newer PV evaluation platforms such as the STEVAL-ISA208V1 or SPV1040-based solutions offering enhanced integration, wider input range, and updated safety certifications.
