TOPSwitch-GX单片开关电源的设计

摘要

The performance of power supply will directly affect the quality of electric products. The tradi-tional power frequency transformer will be eliminated for its large volume, excessive materials, great loss and low efficiency. According to the above disadvantages, a design of single-chip switching power supply is pro-posed by TOPSwitch-GX chip. It has better performance than that of traditional power frequency transformer.%电源性能的优劣直接影响电器产品的质量,传统采用的工频变压器由于体积大、耗材多、损耗大、效率低正逐步被淘汰.针时上述的这些缺点,利用TOPSwitch-GX芯片,提出一种单片开关电源的设计.与传统的工频变压器相比,它具有更加优越的性能.
