Description

The STEVAL-ILL001V1 evaluation board

introduces an innovative solution for driving high

brightness 1 W LEDs (light emitting diodes), using

the VIPer22A-E in a flyback configuration with

output current control. The power supply is

capable of driving a 1 to 8 LED array in the

European voltage range of 185-265 VAC without

modifications. The same VIPer device can also

function within the specifications in the U.S. input

voltage range by using an input voltage doubler.

An innovative control technique is used to adjust

the duty cycle of the output current, in order to dim

the luminosity of the LEDs down to 10% of the

maximum value (STMicroelectronics patent

pending). The proposed driver is suitable for

applications such as landscape lighting, street

lighting, car parks, bollards, garden lighting, large

area displays, etc. Domestic applications such as

room lighting, decorative fixtures and architectural

lighting can also benefit from a dimmable light

source.
