STEVAL-ILL017V1 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.
