三段式開關調(diào)光的高功率因數(shù)非隔離降壓LED驅(qū)動芯片

TP8621是一款具有三段式開關調(diào)光功能的高功率因數(shù)非隔離降壓型LED恒流驅(qū)動芯片。芯片集成了單級有源功率因數(shù)校正電路，特別適合于85VAC~265VAC全電壓輸入范圍的高性能非隔離降壓型LED照明系統(tǒng)調(diào)光應用。\n\nTP8621集成了三段式開關調(diào)光功能。LED輸出電流可以通過普通開關的開關動作在100%、50%和10%之間進行切換。TP8621的調(diào)光方式簡單方便，只需要普通的開關而不需要額外的調(diào)光器，簡化了LED照明系統(tǒng)的設計。\n\nTP8621集成了單級有源功率因數(shù)校正電路，系統(tǒng)可以實現(xiàn)很高的功率因數(shù)和很低的輸入電流總諧波失真。TP8621工作在準諧振開關模式，
