Описание
Evaluation board of 75W digitally controlled constant current LED driver reference design. The principal design objectives of this LED driver board are to deliver considerable performance in terms of efficiency (90%), power factor (>0.97), THD (<20%), wide dimming range (down to 0.5%) and EN55022 EMC precompliance as well as facilitate design optimization over a wide range of operating points with little or no hardware configuration. A reference design based on digital algorithms supported by a programmable STM32 microcontroller therefore seemed to be the ideal solution.
• Wide input voltage range 85 to 265VAC
• Transition Mode PFC
• Buck topology and inverse buck topology
• Open/no-load circuit protection and short-/overload circuit protection
• Soft start implementation
