The EVL6699-HVSL is an evaluation board of a 150 W / 1 A LED driver with wide input mains range. The electrical specification is tailored on a typical hi-power street lighting application.It based on a two stages architecture, a front-end PFC pre-regulator, featuring the L6564H, and a downstream half-bridge LCC resonant converter, featuring the L6699. LCC topology has been chosen because it allows to build, in practice and in brief, a current source that is the natural choice to drive a LED string.Overall, the main features of this design are high efficiency, low open load input power, reduced harmonics compliant with the EN61000-3-2 Class-C and conducted EMC within the relevant EN55022 limits. Another noticeable feature of this LED driver is the extremely wide dimming capability, the board can actually regulate the current from maximum level down to less than 10% with analog dimming and to 1% in PWM dimming. The PWM dimming is perfectly flicker free, because even in case of very low current it is kept continuous (DC) in the LED and thus independent of the frequency of PWM dimming signal.The board also has protection features in case of overload, short-circuit, open loop by each section. For this particular application, all protections in case of intervention have an auto-restart functionality. The board is composed by a mother board ( common to the HVL150W-HVSL ) which houses the power section and a daughter board which house the two controllers, L6564H and L6699.
