Application Report SNVA684A January 2014 1 The Solution to Optimize the load Dynamic Performance in ucc28019a LED lighting Application Richard Yang China Power FAE ABSTRACT With the increasing application on the wide input range of 90 Vac-305vac for the high power PWM dimming LED street lighting , ucc28019a suite very well for this application. However, the PFC inductor noise issue, introduced by the PWM dimming of output load , may be the major concern. In this paper, the root cause of this phenomenon is analyzed based on the small signal model and the Solution is proposed.
The Solution to Optimize t he Load Dynamic Performance in UCC28019A LED Lighting Application Richard Yang China Power FAE ... model is also used to verify the result together with the experiment test in chapter . 4. ...
