AP1684
AC/DC, HIGH PF, HIGH EFFICIENCY LED DRIVER CONTROLLER
Description
Pin Assignments
The AP1684 is a high performance AC/DC power factor corrected
LED driver controller which is driving high voltage bipolar transistor.
The device uses Pulse Frequency Modulation (PFM) technology to
regulate output current while achieving high power factor and low
THD. It operates as a boundary condition mode (BCM) buck controller
which is good for EMI.
The AP1684 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.

The AP1684 features low start-up current, low operation current and
high voltage driving bipolar transistor. 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 AP1684 is available in SO-8 package.
