The electrical specification is tailored on a typical high-power street lighting application. Product status link It is based on a two-stage architecture, consisting of a front-end PFC pre-regulator EVL150W-HVSL and a downstream half-bridge resonant tank converter. The pre-regulator is a transition mode PFC based on constant ON time control, while the resonant converter is an LCC tank that is more suitable than LLC tank to build a current source. Both stages are based on the new STCMB1 combo controller that integrates, in the same device, a transition mode PFC controller and a half-bridge resonant controller. Thanks to the STCMB1, the main features of this design are high efficiency, no-load input power consumption is very low, reduced harmonics compliant with the EN61000-3-2 Class-C, and EMI within the relevant EN55022 limits. Another noticeable feature of this LED driver is the extremely wide dimming capability, actually the board can 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 the case of very low current, it is kept continuous (DC) in the LED and thus independent of the frequency of the 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.
