3.5 W not-isolated offline constant current LED driver based on VIPER17HN

The STEVAL-ILL017V1 demonstration board is a 2 W non-isolated offline constant current LED driver based on the VIPer17. The board operates with an input ranging from 176 V to 264 VAC and provides 500 mA of constant current from a 7 VDC source, suitable for illuminating two LEDs in series.

The VIPer17 device is an offline converter with an 800 V rugged power section, a PWM control, overcurrent protection, overvoltage and overload protection, hysteretic thermal protection, soft-start and safe auto-restart after the removal of a fault condition. The brown-out protection function is embedded into the high voltage start-up.

Burst mode operation and the very low consumption of the device combine to meet standby energy saving regulations. Advanced frequency jittering reduces EMI filter cost.

Key Features

  • Standby power < 50 mW at 265 VAC
  • Operating frequency:60 kHz for L type115 kHz for H type
  • On-board soft-start
  • Adjustable and accurate overvoltage protection
  • Safe auto-restart after a fault condition
  • LED short-circuit protection
  • LED open-circuit protection
  • Input voltage 220 VAC +/- 20%
  • Provides 500 mA constant current for LED
  • 800 V avalanche rugged power section
  • Overtemperature protection
  • PWM operation with frequency jittering for low EMI
  • High precision constant current with +/- 5% tolerance (1 sense resistor and 2 resistor bridges with +/- 1% precision)
