Single Ended PWM Controller Featuring QR Operation and Soft Frequency Foldback

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 controller d • Natural Drain-Source Valley Switching for Lower EMI and Quasi-Resonant Operation\n• Current Mode Control\n• Smooth Frequency Foldback for Low Standby Power and Minimum Output Ripple at No-Load\n• Internal 200 ns Leading Edge Blanking on Current Sense\n• Wide UVLO Levels: 9.3 to 15 V Typical\n• 250;
