AP1685
Description
OFFLINE, HIGH PF, HIGH EFFICIENCY LED DRIVER IC
Pin Assignments
The AP1685 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.

7 Drain
The AP1685 internally integrates a 500V high voltage MOSFET which
can realize a lower BOM cost. The AP1685 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.
The AP1685 features low start-up current, low operation current. It
adopts valley on switching mode to achieve high efficiency. It also has
rich protection features including over voltage, short circuit, over
temperature protection.
The AP1685 is available in SO-7 package.
