STMicroelectronics EVLMG4L-IBCKFL Buck Converter Buck Converter EVLMG4L-IBCKFL

The STMicroelectronics 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.

High precision output current with output current variation better than 5 percent
No heatsink required
RoHS compliant
