Description
OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER IC
Features
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.
The AP1695 internally integrates 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.
The AP1695 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 AP1695 provides the dimmable LED driver with a wide dimmer
compatibility including leading edge and trailing edge dimmer. The
AP1695 can achieve deep dimming down to 1%, while the dimming
curve is compliant with the standard of NEMA SSL6.
