STMicroelectronics STEVAL-ILL013V1

Overview

STEVAL-ILL013V1 from STMicroelectronics is an 80 W offline dimmable LED driver demonstration board implementing a high-power-factor (0.982 at 230 V/50 Hz) PFC + non-isolated SMPS topology based on the L6562A controller IC. It delivers constant current outputs of 350 mA, 700 mA, or 1 A across 88–265 VAC input, achieves ~90% efficiency, and complies with EN55015 and EN61000-3-2 standards for lighting systems.

For engineers reviewing the STEVAL-ILL013V1 datasheet, STEVAL-ILL013V1 pinout, STEVAL-ILL013V1 application, or STEVAL-ILL013V1 equivalent, this board serves as a validated reference design for high-efficiency, universal-input, dimmable LED drivers targeting commercial and industrial solid-state lighting.

Technical Context

The board implements a two-stage architecture: an active boost PFC front-end using the L6562A to meet harmonic current limits, followed by a modified BUCK converter for constant-current LED regulation. Input rectification is via BR1 (1A/250V bridge), and EMI filtering includes X/Y capacitors (C102, C103, C104) and common-mode chokes (TR1).

Dimming is supported via universal PWM input (external signal required), with brightness adjustable from 0–100%. Current setting is configured via jumpers JP1–JP4 per Table 1, enabling discrete selection of 350 mA, 700 mA, or 1 A output without component changes.

FAQ

Is STEVAL-ILL013V1 isolated or non-isolated?

STEVAL-ILL013V1 is a non-isolated SMPS design. Its output shares a common reference with the AC input ground, making it unsuitable for applications requiring reinforced insulation or user-accessible low-voltage outputs. Safety-critical implementations must incorporate external isolation or enclosure-level protection per IEC 61347.

What is the role of the L6562A on this board?

The L6562A is a transition-mode PFC controller used in the front-end boost stage. It regulates the input current waveform to achieve near-unity power factor and low THD, enabling compliance with harmonic emission standards while delivering a stabilized ~400 V DC bus for the downstream LED driver stage.

Can this board drive LEDs with different forward voltages?

Yes - the board supports LED strings with total forward voltage up to ~350 VDC (limited by C208 and C113 ratings). Output voltage headroom depends on selected current and thermal derating; maximum string voltage is determined by the BUCK stage's duty cycle and input bus level (~400 V).

Does STEVAL-ILL013V1 include EMI filtering components?

Yes - it integrates a full EMI filter: X-capacitors (C102, C104), Y-capacitors (C101, C103), and a dual-winding common-mode choke (TR1, 2×22 mH/1 A). This enables direct compliance with EN55015 Class B conducted/radiated emission limits without external filtering.
