A Product Line of Diodes Incorporated
AC/DC, HIGH PF, HIGH EFFICIENCY LED DRIVER CONTROLLER
Description
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 pensation circuitry while maintaining stability. It can meet the...
