Beschreibung

The EVLMG4L-IBCKFL evaluation board is designed to be connected to a high voltage input DC source (e.g. PFC pre-regulator) to drive one high voltage, high power LED string with very accurate and adjustable (dimmable) current.The control algorithm is provided by HVLED002 and applied to MASTERGAN4L to convert the input power into output current efficiently.The VIPer06X high voltage converter provides auxiliary supply to the entire circuit.A 0-10V DC voltage can be used to dim the output current from 100% to 10%; leaving the dimming connector open, the maximum output current is provided.Input voltage UVLO as well as output overvoltage and undervoltage protections are implemented.
