LM3444BOOST-REF, 6.2W LM3444 MR16 Boost Reference Design for Non-Dimming/Dimming LED Applications. This design 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
