STMicroelectronics STEVAL-ILL065V1

Overview

STEVAL-ILL065V1 from STMicroelectronics is an evaluation board for the LED5000 constant-current LED driver IC, implementing BB+ boost topology to deliver up to 3 A DC output current with ±3% accuracy over temperature, 850 kHz fixed switching frequency, and 200 mV typical current sense voltage drop for high-efficiency LED lighting control in industrial and architectural applications.

For engineers reviewing the STEVAL-ILL065V1 datasheet, STEVAL-ILL065V1 pinout, STEVAL-ILL065V1 application, or STEVAL-ILL065V1 equivalent, this board enables rapid validation of LED5000-based 5.5–48 V input, PWM-dimmable, ceramic-capacitor-compatible LED drivers with thermal shutdown, short-circuit protection, and zero-current inhibit functionality.

Technical Context

The STEVAL-ILL065V1 implements a BB+ (Boost-Buck Plus) topology using the LED5000 monolithic controller, supporting wide 5.5–48 V input while regulating precise constant current up to 3 A via external sense resistor feedback. Its peak current mode architecture ensures stable operation with ceramic output capacitors.

Integrated PWM dimming circuitry provides direct brightness control, while inhibit functionality enables true zero quiescent current shutdown. Protection features include cycle-by-cycle overcurrent detection, thermal shutdown at 150 °C, and robust short-circuit handling without external components.

FAQ

What is the primary function of the STEVAL-ILL065V1?

The STEVAL-ILL065V1 is an evaluation board for the LED5000 IC, configured in BB+ boost topology to drive high-power LED strings with precise constant current up to 3 A. It demonstrates full functionality including PWM dimming, thermal protection, short-circuit recovery, and ceramic capacitor compatibility - not a standalone IC or discrete component.

Does the board support analog dimming or only PWM?

The STEVAL-ILL065V1 supports only PWM dimming, as implemented by the LED5000 IC. No analog (DC) dimming capability is present - brightness control requires a clean, logic-level PWM signal applied to the DIM pin, with frequency above 100 Hz to avoid visible flicker and duty cycle adjustable from 0% to 100%.

Can the output current be adjusted, and how?

Yes, output current is set externally via a sense resistor (R_SENSE) connected between the LED cathode and the FB pin. Using the 200 mV nominal sense voltage, R_SENSE = 0.2 V / I_OUT; for example, 66.7 mΩ yields 3 A. The board includes solder jumpers to accommodate different R_SENSE values and corresponding compensation adjustments.

Is the STEVAL-ILL065V1 RoHS compliant and suitable for production use?

Yes, the STEVAL-ILL065V1 is RoHS compliant per its data brief and intended for design-in reference and pre-compliance testing. While not a production-grade module, its layout, BOM, and thermal design are representative of ST-recommended practices for LED5000-based systems targeting industrial lighting certifications.
