STEVAL-ILL085V1 STMicroelectronics

STEVAL-ILL085V1 Wide input and wide output voltage LED driver with high power factor and low THD based on HVLED001A Data brief Description 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 Features regulation. The standby consumption is below AC input voltage range: 90 V to 300 V 0.5 W. LED voltage / current: 60 V-105 V / 700 mA Constant LED current: 700 mA 2% Short-circuit and open circuit LED protection is included, and board efficiency is above 90%. Power factor: > 0.95 Input current THD: < 10% Smart pins are included for LED streetlight Standby consumption: < 0.5 W ON/OFF switching and remote dimming. Open-circuit and short-circuit protection The design is unique in terms of form factor and Provision for smart features: ON / OFF / proven high thermally stability. DIMMING RoHS compliant 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.
