NEW PRODUCT A Product Line of Diodes Incorporated AP1685 Description OFFLINE, HIGH PF, HIGH EFFICIENCY LED DRIVER IC Pin Assignments The AP1685 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) which is good for EMI. (Top View) S1 7 Drain The AP1685 internally integrates a 500V high voltage MOSFET which can realize a lower BOM cost. The AP1685 provides accurate constant current (CC) regulation while removing the opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability.
