STEVAL-ILL0V Wide input and wide output voltage LED driver with high power factor and low THD based on HVLED00A Data brief Features AC input voltage range: 90 V to 00 V LED voltage / current: 0 V-0 V / 00 ma Constant LED current: 00 ma ± % Power factor: > 0.9 Input current THD: < 0% Standby consumption: < 0. W Open-circuit and short-circuit protection Provision for smart features: ON / OFF / DIMMING RoHS compliant Description The STEVAL-ILL0V board is a constant current LED driver with high power factor and low input current THD for wide range input voltage. It uses the HVLED00A power management IC for power quality improvement. This board includes other discrete power devices produced by STMicroelectronics, including MOSFETs (STPN90K), diodes (STTHL0 and STTHL0), transil (PKE00), CV / CC controller (TSM0) and LDO (LM9ADR). The board works on 0 V to 0 V LED voltage and 00 ma constant current with ± % current regulation. The standby consumption is below 0. 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 thermally stability. In terms of power quality, the power factor is above 0.9 and the THD is less than 0%. It is well within the harmonic limits set by IEC000- - Class C for lighting. November 0 DocID000 Rev / For further information contact your local STMicroelectronics sales office www.st.com
