Housed in a SO−14 package, the DAP018X represents an enhanced version of the currently available Speedking controller, the DAP011.

With an internal structure operating at a fixed 65 kHz or 100 kHz frequency, the controller directly connects to the high−voltage rail for a lossless and clean startup sequence. Current−mode control also provides an excellent input audio−susceptibility and inherent pulse−by−pulse control.

Internal ramp compensation easily prevents sub−harmonic oscillations from taking place in continuous conduction mode designs. On top of these features, the device takes advantage of the auxiliary winding negative swing to let the user adjust the maximum power the converter can deliver in high line conditions (OPP).
