TY72011AP2 Features

* TY72011AP2 The TY72011AP2 combines a true Current Mode Control modulator and a demagnetization detector to ensure full Discontinuous Conduction Mode in any load/line conditions and minimum drain voltage switching (Quasi-Resonant operation). Thanks to its inherent Variable Frequency Mode (VFM), the
