The EVL150W-HVSL is an evaluation board of a150 W / 1 A LED driver with wide input mains range. The electrical specification is tailored on a typical high-power street lighting application. It is based on a two-stage architecture, consisting of a front-end PFC pre-regulator and a downstream half-bridge resonant tank converter. The pre-regulator is 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. Universal input mains range: 90 to 264 Vac -frequency 45 to 65 Hz
Half-bridge topology: LCC
Max. output voltage and current: 150 V at 1 A continuous operation
No-load mains consumption: < 0.5 W
THD < 10% at 230 Vac from 30 to 100% of the full load
No need of auxiliary SMPS (Viper or equivalent)
Efficiency: >91% at full load
