OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER CONTROLLER
Features
The AP1694 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) controller which is good for EMI.
The AP1694 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 AP1694 features low start-up current, low operation current. It
adopts dynamic base driver control technology and valley on
switching mode to achieve high efficiency. It also has rich protection
NEW PRODUCT
features including over voltage, short circuit, over temperature
protection.
The AP1694 provides the dimmable LED driver with a wide dimmer
compatibility including leading edge and trailing edge dimmer. The
AP1694 can achieve deep dimming down to 1%, while the dimming
curve is compliant with the standard of NEMA SSL6.
The AP1694 is available in SO-8 package.
