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) which is good for EMI.

Features

• Boundary Conduction Mode (BCM) Operation to Achieve High-efficiency

• High PF and Low THD (PF>0.9, THD<30)

• High Efficiency without Dimmer

• Wide Range of Dimmer Compatibility

• Dimming Curve Compliant with NEMA SSL6

• Low Start-up Current

• Tight LED Current

• Tight LED Open Voltage

• Valley-mode Switching to Minimize the Transition Loss

• Internal Integrated 2A/500V MOSFET can Cover up to 10W

• Easy EMI

• Internal Protections:

◾ Under Voltage Lock Out (UVLO)

◾ Leading-edge Blanking (LEB)

◾ Output Short Protection

◾ Output Open Protection

◾ Over Temperature Protection

• Flexible for Design with Small Form Factor and Very Low BOM Cost

• Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

• Halogen and Antimony Free. “Green” Device (Note 3)

Applications

• Mains Dimmable LED Lighting
