AP1695-20C
OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER IC
Description
The AP1695-20C 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 AP1695-20C internally integrates a high voltage MOSFET which
can realize a lower BOM cost. The AP1695-20C 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 AP1695-20C 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 AP1695-20C provides the dimmable LED driver with a wide
dimmer compatibility including leading edge and trailing edge dimmer.
The AP1695-20C can achieve deep dimming down to 1%, while the
dimming curve is compliant with the standard of NEMA SSL6.
The AP1695-20C is available in SO-7 package.
