onsemi 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). The internal High-Voltage current source provides a reliable charging path for the Vcc capacitor and ensures a clean and short start-up sequence without deteriorating the efficiency once off.| Part No. | TY72011AP2 |

FEATURES
TY72011AP2 Thanks to its inherent Variable Frequency Mode (VFM), the controller decreases its operating frequency at constant peak current whenever the output power demand diminishes. Associated with automatic multiple valley switching, this unique architecture guarantees minimum switching losses and the lowest power drawn from the mains when operating at no-load conditions. Finally, the continuous feedback signal monitoring implemented with an over-current fault protection circuitry (OCP) makes the final design rugged and reliable. An internal Over Voltage Protection (OVP) circuit continuously monitors the Vcc pin and stops the IC whenever its level exceeds 40 V. The internal OVP connection is also externally available to precisely adjust the final protection level to the designer needs.
