AP1694AS-13集成电路（IC）的LED驱动器规格书PDF中文资料

描述 Description

The AP1694AS-13 is a high performance AC-DC power factor corrector for mains dimmable LED driver applications. The device uses Pulse Frequency Modulation (PFM) technology to regulate output current while achieving high power factor and low THD. It operates as a BCM (Boundary Conduction Mode) controller which is good for EMI.
