STMicroelectronics STEVAL-ILL076V1

Overview

STEVAL-ILL076V1 from STMicroelectronics is an evaluation board implementing a 40 W, ultra-slim flyback LED driver converter using the HVLED001 quasi-resonant controller. It accepts 180–264 V_RMS AC input (45–66 Hz), delivers regulated 56 V / 720 mA DC output, achieves >92% full-load efficiency and >0.95 power factor with <10% THD, and provides 4 kV isolation for LED string bus power supply applications.

For engineers reviewing the STEVAL-ILL076V1 datasheet, STEVAL-ILL076V1 schematic, STEVAL-ILL076V1 application, or STEVAL-ILL076V1 equivalent, this board serves as a validated reference design for high-PF, primary-side regulated offline LED drivers targeting space-constrained industrial and architectural lighting systems.

Technical Context

The board implements a single-stage, high-power-factor flyback topology with primary-side regulation (PSR) enabled by the HVLED001 controller, eliminating optocouplers. Transformer design and PSR precision deliver ±3% output voltage regulation across line (180–264 V_RMS) and load (10–100%) variations.

EMI performance is pre-compliant with EN55022 Class B limits; safety clearances meet EN60950 requirements. Protection features include auto-restart short-circuit response and input overvoltage shutdown, with no-load consumption <400 mW at 230 V_IN.

FAQ

Is STEVAL-ILL076V1 still in active production?

No - STEVAL-ILL076V1 is marked obsolete per ST's official documentation (DocID028372 Rev 1, Sept 2015). It remains available through authorized distributors for legacy design support and reference use, but no new revisions or long-term supply commitments are offered.

Can STEVAL-ILL076V1 be used with non-LED loads?

It is specifically optimized for constant-current LED string bus supplies. While it delivers regulated 56 V DC, its protection logic, loop compensation, and transformer design assume capacitive + LED load characteristics; using it with generic DC-DC loads may compromise stability, efficiency, or safety margin.

What safety certifications does this board meet?

The board meets clearance and creepage requirements per EN60950-1, and conducted EMI is pre-compliant with EN55022 Class B. It is not CE-marked or UL-recognized as a standalone product; end-equipment certification remains the responsibility of the system integrator.

Where can I find the schematic and bill of materials?

The complete schematic, BOM, PCB layout files, and test reports are provided in the official data brief DocID028372 Rev 1, freely available on ST's website under the STEVAL-ILL076V1 product page, with no registration required.
