AP1694AS-13 Datasheet | Diodes Incorporated

NEW PRODUCT OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER CONTROLLER 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. The AP1694AS-13 provides accurate constant current (CC) regulation while removing the opto-coupler and secondary control circuitry. It also eliminates the need for loop pensation circuitry while maintaining stability. It can meet the requirement of IEC6100-3-2 harmonic standard. The AP1694AS-13 Features low start-up current and low operation current. It adopts valley on switching mode to achieve high efficiency. It also has rich protection Features including overvoltage, short circuit, and over-temperature protection. The AP1694AS-13 provides the dimmable LED driver with a wide dimmer patibility including leading edge and trailing edge dimmer. The AP1694AS-13 can achieve deep dimming down to 1%, while the dimming curve is pliant with the standard of NEMA SSL6. The AP1694AS-13 is available in SO-8 package.
