NOT RECOMMENDED FOR NEW DESIGN USE AP1694AS-13 AP1694 OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER CONTROLLER Description Features The AP1694 is a high performance AC/DC power factor corrector for Primary Side Control for Output Current Regulation without Opto- mains dimmable LED driver applications. The device uses Pulse coupler Frequency Modulation (PFM) technology to regulate output current Boundary Conduction Mode (BCM) Operation to Achieve High- while achieving high power factor and low THD. It operates as a BCM efficiency (Boundary Conduction Mode) controller which is good for EMI. High PF and Low THD High Efficiency without Dimmer The AP1694 provides accurate constant current (CC) regulation while Wide Range of Dimmer Compatibility removing the opto-coupler and secondary control circuitry. It also Dimming Curve Compliant with NEMA SSL6 eliminates the need of loop compensation circuitry while maintaining Low Start-up Current stability. It can meet the requirement of IEC6100-3-2 harmonic Tight LED Current standard. Tight LED Open Voltage BJT Transistor Driver The AP1694 features low start-up current, low operation current. It Dynamic Base Driver Control adopts dynamic base driver control technology and valley on Valley-mode Switching to Minimize the Transition Loss switching mode to achieve high efficiency. It also has rich protection Easy EMI features including over voltage, short circuit, over temperature Internal Protections: protection. Under Voltage Lock Out (UVLO) Leading-edge Blanking (LEB) The AP1694 provides the dimmable LED driver with a wide dimmer Output Short Protection compatibility including leading edge and trailing edge dimmer. The Output Open Protection AP1694 can achieve deep dimming down to 1%, while the dimming Over Temperature Protection curve is compliant with the standard of NEMA SSL6. Flexible for Design with Small Form Factor and Very Low BOM The AP1694 is available in SO-8 package. Cost Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
