Product details
Overview
STEVAL-ILL049V1 from STMicroelectronics is an LED driver evaluation board based on the LED6001 constant-current controller IC, implementing a selectable boost or SEPIC topology to drive up to 10 white LEDs (40 V OVP) at 350 mA with PWM or analog dimming. It features onboard ambient light sensing via photo-transistor and thermal protection using NTC-based analog dimming control.
For engineers reviewing the STEVAL-ILL049V1 datasheet, STEVAL-ILL049V1 pinout, STEVAL-ILL049V1 application, or STEVAL-ILL049V1 equivalent, this board serves as a validated reference design for off-grid street lighting, signage, advertising panels, and gaming illumination systems requiring compact, high-efficiency single-string LED driving with fault monitoring and adaptive dimming.
Technical Context
The board implements the LED6001's dual-mode DC-DC architecture-user-selectable between boost and SEPIC topologies-enabling flexible input-to-output voltage relationships (6–24 VIN, up to 40 VOUT). Fault management includes open-LED, feedback disconnection, output short-circuit (SEPIC only), and overcurrent detection, all signaled via the XFAULT pin.
Dimming is implemented through two independent paths: 0–100% PWM control applied to PWMI, and 10:1 analog dimming via ADIM voltage (0.3–3.0 V), which modulates LED current by adjusting the internal reference. Ambient light sensing uses SFH3710-3/4 photo-transistor coupled to an LDO3-supplied bias network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6 V to 24 V DC - supports wide-range off-grid and industrial DC supplies including 12 V and 24 V battery/bus systems. |
| Output Current | 350 mA constant - precisely regulated single-channel LED current enabling stable brightness across varying forward voltage stacks. |
| Topology Support | Boost or SEPIC - selectable via JP4; SEPIC enables output voltage below, equal to, or above input, critical for variable LED string configurations. |
| OVP Threshold | 40 V - protects against overvoltage during transient conditions or open-circuit faults in strings up to 10× white LEDs (~3.8 V each). |
| Efficiency | Up to 92% (boost mode) - minimizes thermal load and power loss in space-constrained lighting enclosures. |
| Dimming Methods | PWM (0–100%) + analog (10:1) - provides flicker-free smooth dimming and compatibility with both microcontroller PWM outputs and analog control signals. |
| Fault Detection | Open LED, feedback disconnect, overcurrent, output short (SEPIC only) - latches or auto-restarts per configuration, simplifying system-level safety logic. |

FAQ
What topologies does the STEVAL-ILL049V1 support, and how are they selected?
The board supports both boost and SEPIC converter topologies. Selection is made via jumper JP4: open for boost mode, closed for SEPIC. This allows designers to match the topology to their specific input/output voltage relationship-SEPIC is required when output voltage may fall below or exceed input, such as in variable-input solar-powered lighting.
How is ambient light sensing implemented on this board?
Ambient light sensing uses the SFH3710-3/4 photo-transistor (Q3) biased by the LDO3 regulator (U1 pin 14). Its collector output connects to the ADIM pin, enabling automatic dimming adjustment based on ambient light level without external ADC or microcontroller intervention.
Does the board provide thermal protection for the LED string?
Yes-thermal protection is implemented via an NTC thermistor (RT1, Murata NCP18WB473J03RB) connected to the ADIM pin. As temperature rises, RT1 resistance drops, reducing the ADIM voltage and proportionally lowering LED current to prevent overheating and extend LED lifetime.
What fault conditions does the XFAULT pin indicate?
The XFAULT pin asserts low for four monitored faults: open LED string, feedback loop disconnection (OVFB/CSNS), LED overcurrent, and output-to-ground short circuit (in SEPIC mode only). The fault remains latched until reset via VIN cycle or PWM signal reinitialization, enabling reliable system-level fault logging.
