AP1695: 500V Offline, High PF, High Efficiency Dimmable LED Driver IC

The AP1695 is a high performance power factor (PF) corrected LED driver for offline dimmable retrofit lamps. It uses a boundary conduction mode (BCM)/pulse frequency modulation (PFM) technology to regulate output current with high power factor/low THD, and low EMI. The AP1695 uses primary side regulation to regulate the LED current, removing the need for optocouplers and loop compensation therefore reducing the total solution cost.
