摘要：
The driving circuit for ten high-power white LED bulbs which are connected in series is designed. The core chip used is XLT604 and the peripheral circuits such as rectification circuit, dimming circuit are also designed. The modulation of LED is via the outer control voltage and therefore it belongs to a kind of linear dimming method. The parameters of key devices, such as the sampling resistance R6, the oscillation resistance R4, the inductance L1 and the fast restoring diode D5, are selected carefully according to relevant theoretical formula.
