STEVAL-ILL017V1

Демонстрационная плата неизолированного драйвера светодиода 3.5Вт на базе VIPER17HN.

STEVAL-ILL017V1 demonstration board is a 2W non isolated offline constant current LED driver based on the VIPer17. The board operates with an input ranging from 176V to 264VAC and provides 500mA of constant current from a 7VDC source, suitable for illuminating two LEDs in series. The VIPer17 device is an offline converter with an 800V rugged power section, a PWM control, overcurrent protection, overvoltage and overload protection, hysteretic thermal protection, softstart 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.
