Description

The STEVAL-ILL038V1 demonstration board

implements a 100 W LED switched-mode power

supply (SMPS) based on the L6585DE. This

device embeds a high-performance transition

mode (TM) Power Factor Correction (PFC)

controller, Half-Bridge (HB) controller and all the

relevant drivers necessary to build a combo IC.

The L6585DE embeds a wide range of features to

provide an energy-saving and cost-effective

solution for LED SMPS.

The PFC section of this IC has superior

performance in terms of harmonic content

mitigation. High Power Factor (PF) and Total

Harmonic Distortion (THD) reduction are obtained

as required by international norms, especially

concerning universal input voltage operations.

The TM PFC operation and high-efficiency

performance of the half-bridge topology provide

very good overall circuit efficiency.

In order to guarantee maintenance-free operation

required by this kind of application during the

LED’s lifetime, the STEVAL-ILL038V1 board

doesn’t use any electrolytic capacitors which have

been replaced by safer film capacitors.

Other features, such as half-bridge overcurrent

with frequency increase and PFC overvoltage,

allow designers to build a reliable and flexible

solution with a reduced component count.
