The demonstration board includes a LM3429 device that converts 9VDC to 36VDC input to a 700mA constant current output designed to operate a load of three to four series LEDs.
This reference design is ideal for any LED application that runs off of a 12V or 24V rail. This is a 4-layer board having input voltage and ground as the two internal planes. The design has been made assuming there are analog dimming requirements.
This design works with the Nuventix SynJet module which serves as the cooling element for an LED luminaire or bulb replacement for the standard MR16, PAR20, PAR25, PAR30 or PAR38 form factors
