Description

Housed in a SO−14 package, the SCY99063D65R2G is an enhanced version of the currently available Speedking controller, the DAP011. It has an internal structure operating at a fixed frequency of 65 kHz or 100 kHz. The controller directly connects to the high−voltage rail for a lossless and clean startup sequence. Current−mode control provides excellent input audio−susceptibility and inherent pulse−by−pulse control. It also features internal ramp compensation to prevent sub−harmonic oscillations in continuous conduction mode designs. Additionally, the device allows the user to adjust the maximum power the converter can deliver in high line conditions (OPP) by taking advantage of the auxiliary winding negative swing.
