NEW PRODUCT Description A Product Line of Diodes Incorporated AP1684A AC/DC, HIGH PF, HIGH EFFICIENCY LED DRIVER CONTROLLER Pin Assignments The AP1684A is a high performance AC/DC power factor corrected LED driver controller. The device uses Pulse Frequency Modulation (PFM) technology to regulate output current while achieving high power factor and low THD. It operates as a boundary condition mode (BCM) buck controller which is good for EMI. The AP1684A 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. It can meet the requirement of IEC6100-3-2 harmonic standard. The AP1684A features low start-up current, low operation current.
