基于TEA1750T的LED驱动电源设计

Design of the LED Driver Power Base on TEA1750T

针对LED对驱动电源特性要求,设计出基于TEA1750T的恒压、恒流LED驱动电源、并具有LED温度负反馈功能,防止LED温度过高。TEA1750T集成了功率因数校正(PFC)控制器,以及反激电路(Flyback)控制器。由于TEA1750T集成度极高,只需极少量的外部元件,即可实现高性价比的恒压、恒流电源设计,并对实验机样进行了实验研究。

The LED driver based on chip TEA1750T is designed aiming at the constant current、constant voltage characteristic of LED.The TEA1750T combines a controller for Power Factor Correction（PFC） and a Flyback Controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components,and then the experiment circuit is tested.
