Description
The STEVAL-ILL037V1 demonstration board
implements a 3.2 W (16 V / 0.2 A) wide range
LED driver to support from 3 to 5 LEDs for LED
lamps (e.g. E27 and GU10).
The HVLED805 is an offline all-primary sensing
switching regulator, specific to offline LED drivers,
based on quasi-resonant ZVS (zero voltage
switching at switch turn-on) flyback topology, due
to its simplicity and low cost.
