AP1694
OFFLINE, HIGH PF, HIGH EFFICIENCY DIMMABLE LED DRIVER CONTROLLER
Description
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 (BCM) Operation to Achieve Highefficiency
•
High PF and Low THD
•
High Efficiency without Dimmer
The AP1694 provides accurate constant current (CC) regulation while
•
Wide Range of Dimmer Compatibility
removing the opto-coupler and secondary control circuitry. It also
•
Dimming Curve Compliant with NEMA SSL6
eliminates the need of loop compensation circuitry while maintaining
•
Low Start-up Current
stability. It can meet the requirement of IEC6100-3-2 harmonic
•
Tight LED Current
standard.
•
Tight LED Open Voltage
•
BJT Transistor Driver
•
Dynamic Base Driver Control
•
Valley-mode Switching to Minimize the Transition Loss
•
Easy EMI
(Boundary Conduction Mode) controller which is good for EMI.
NEW PRODUCT
Primary Side Control for Output Current Regulation without Optocoupler
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
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.
