AP1694中文资料off-line-led-drivers数据手册Diodes规格书

描述 Description

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.

\t 

\tThe 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.

\t 

\tThe 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.

\t 

\tThe 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.

\t 

\tThe AP1694 is available in SO-8 package.
