AP1695 (Obsolete)

Description

"The AP1695 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 AP1695 internal integrated a 500V high voltage Mosfet which can realize a lower BOM cost. The AP1695 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."

Feature(s)

• Unique Constant On Time (COT) Control Provide wide range of dimmer compatibility and deep dimming down to 1%

• flexible topology design,supporting isolated solution (Flyback) and Non-isolated solution (Buck-boost & Buck)
• Boundary Conduction Mode (BCM) Operation Delivers high efficiency solutions with small EMI components
• Internal MOSFET support low power LED light

Application(s)

Mains Dimmable LED Lighting
