AP1690
SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER
FOR DIMMABLE LED DRIVER
Description
The AP1690 is a high performance AC/DC universal input Primary
Side Regulation Power Factor Controller for dimmable LED driver
applications.
The AP1690 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. The AP1690 achieves excellent regulation and high
efficiency, yet meets the requirement of IEC61000-3-2 harmonic
standard.
The AP1690 features low start-up current, low operation current and
high efficiency. It also has rich protection features including over
voltage, short circuit, over current, over temperature protection etc. In
order to regulate the output current of LED current with the phase of
dimmer, pin 2 and pin 3 are used to set the peak current of
transformer according to the voltage applied to these two pins.
The AP1690 is available in SO-8 package.
