概述

This reference design was based on the released LM3444 IC. It was developed to minimize 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 design generates a continuous LED current when a 220uF 35V electrolytic capacitor is placed across the output. The circuit operates in a constant output power mode. The output power is fixed at about 6W.

特性
  • Boost design topology
  • Tested with Electronic Transformers (12VAC output)
  • Work with off the shelf dimmers with no flicker, stable operation
  • Flicker-free operation with common Electronic Low Voltage dimmers, and Electronic Transformers
