Description
This user manual describes the dimmable LED driver solution for fixtures with theSSL5251T LED driver controller.The board is an example of a buck-boost topology with the controller ICs placed at thehigh side. The IC ground pin (pin 2) is the switching node.The typical features of the single-stage buck-boost topology are:• Low Total Harmonic Distortion (THD)• Small bus capacitor and large output capacitor• Fixed on-time with small modulation for low mains current harmonics
