The AP1514 is capable of driving multiple series
connected LEDs. The AP1514 sense rectified AC
input source voltage to modulate LED current which
can in phase input voltage to implement high power
factor and high efficiency. AP1514 is a high
voltage process chip with internal regulator to
generate bios voltage which supports IC internal
circuit. The AP1514 also has internal power switch
to minimize external components.
The AP1514 consists of four switches to modulate
output LEDs series numbers and adjust current level
to fit input sin wave. The AP1514 also has
feed-forward compensation to compensate line
voltage variation. The AP1514 has LD/SD serve
as shut down controlled by external intelligent
control box. The LD/SS also has linear dimming
controller interface for DALI control dimming.
The package of AP1514 is TSSOP-16. Which
suitable for LED lighting like MR-16, E-17,E27…and so on applications.
