■Input frequency: 50 Hz - 60 Hz

■Output power: 3.2 W

■Expected efficiency: 85%

■Output voltage: ~16 Vdc (from 3 to 5 LEDs)

■Output current: 200 mA

■For E26/E27/GU10 LED lamps

■RoHS compliant

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.
