STMicroelectronics STEVAL-ILL080V1

Overview

STEVAL-ILL080V1 from STMicroelectronics is an 18 W, non-isolated, high-power-factor LED driver evaluation board designed as a T8 fluorescent tube replacement. It delivers 200 mA constant current with <1% 100 Hz ripple into an 83 V ±10% LED string, uses HVLED001A quasi-resonant flyback controller and STF10LN80K5 MOSFET, and achieves >85% full-load efficiency at 180–264 V_AC, 45–66 Hz input.

For engineers reviewing the STEVAL-ILL080V1 datasheet, STEVAL-ILL080V1 pinout, STEVAL-ILL080V1 application, or STEVAL-ILL080V1 equivalent, key selection criteria include zero-ripple current delivery, SEPIC topology for THD <20%, no-load power <300 mW at 230 V_AC, short-circuit auto-restart protection, and RoHS-compliant sealed-tube compatibility.

Technical Context

The board implements a non-isolated, high-power-factor SEPIC converter optimized for enclosed LED tube replacements. It leverages the HVLED001A's quasi-resonant control to minimize switching losses and enable precise current regulation without secondary-side feedback, while the STF10LN80K5 (800 V, 10 A) handles high-voltage primary-side switching under 264 V_AC mains surges.

Input current ripple steering reduces EMI, allowing compact input filtering; overvoltage, undervoltage, and short-circuit protections are embedded in the HVLED001A, eliminating need for external fault management circuitry. No-load output voltage is fixed at 110 V, enabling safe open-circuit operation in sealed fixtures.

FAQ

Is STEVAL-ILL080V1 isolated or non-isolated?

STEVAL-ILL080V1 is a non-isolated design using SEPIC topology. It lacks transformer-based galvanic isolation and is intended only for double-insulated, fully enclosed LED tube replacements where user access to internal circuitry is prohibited by mechanical design and safety certification.

What is the role of the HVLED001A controller on this board?

HVLED001A provides quasi-resonant flyback control with integrated protections: brown-out detection, overvoltage shutdown (for surges), and short-circuit auto-restart. It enables zero-ripple current regulation without optocoupler feedback by sensing primary-side current and voltage waveforms.

Can STEVAL-ILL080V1 drive multiple parallel LED strings?

No. The board is configured for single-string operation only, delivering 200 mA into one 75–93 V string. Driving parallel strings would unbalance current distribution and exceed the HVLED001A's regulation capability, risking thermal runaway and premature LED failure.

Does STEVAL-ILL080V1 support dimming functionality?

No. This evaluation board has no provision for analog or PWM dimming input. It is a fixed-output, constant-current source optimized for flicker-free full-brightness operation in retrofit tube applications per its original design intent.
