Abstract From the perspective of product design, the characteristics and working principle of chip, SSL1750T of NXP, are introduced in detail. The design method of high power LED driver based on the chip, especially the design of the PFC inductor and fly-back transformer, are detailed. At last, an actual case of LED street-lamp driver design based on SSL1750T is given. Practicability of the design method is certified by the actual test data and waveform.
