Wide input and wide output voltage LED driver with high power factor and low THD based on HVLED001A

STEVAL-ILL085V1

Overview

The STEVAL-ILL085V1 board is a constant current LED driver with high power factor and low input current THD for wide range input voltage. It uses the HVLED001A power management IC for power quality improvement.

This board includes other discrete power devices produced by STMicroelectronics, including MOSFETs (STP21N90K5), diodes (STTH3L06 and STTH1L06), transil (P6KE400), CV / CC controller (TSM101) and LDO (LM2931AD33R). The board works on 60 V to 105 V LED voltage and 700 mA constant current with ± 2% current regulation. The standby consumption is below 0.5 W.
Short-circuit and open circuit LED protection is included, and board efficiency is above 90%.
Smart pins are included for LED streetlight ON/OFF switching and remote dimming.
The design is unique in terms of form factor and proven high thermal stability.
In terms of power quality, the power factor is above 0.95 and the THD is less than 10%. It is well within the harmonic limits set by IEC61000-3-2 Class C for lighting.
