LM3401-MR16DEMO/NOPB Datasheet PDF - TI

●The LM3401-MR16DEMO/NOPB is a LM3401 MR16 bulb reference design for non dimming & dimming LED applications. This reference design was based on the released LM3401 evaluation board. A PCB was created that fits into the MR16 cavity. For fast bench set up, the LM3401 evaluation board can be modified with the LM3401 MR16. This design was developed to minimise the current spikes coming out of an electronic transformer to less than 5A, which is a typical transformer rating, when driving an LED MR16 circuit. The off the shelf LED MR16 solutions exhibit spikes that significantly exceed a transformer"s maximum rated output current which will degrade the reliability of the transformer and reduce its operating lifetime. This LM3401 evaluation board is designed to operate (flicker free) with common electronic low voltage dimmers and electronic transformers.
