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.
