Product Overview

150V, 150W LED driver evaluation board using the STCMB1 transition mode PFC and HBR resonant tank combo controller. It is an evaluation board of a 150W / 1A 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 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. 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.
  • Universal input mains range from 90VAC to 264VAC, frequency 45 to 65Hz
  • LCC half-bridge topology
  • No-load mains consumption of < 0.5W
  • THD < 10% at 230VAC from 30 to 100% of the full load
  • No need of auxiliary SMPS (Viper or equivalent)
  • Efficiency of >91% at full load, no electrolytic capacitors for long term reliability
  • Conducted EMC within EN55022-Class-C limits, meets EN60950
  • Analog, resistive, PWM (open collector) dimming
  • Constant current and constant voltage feedback loops
  • Dimension is 69 x 157mm, 28mm components maximum height
