Datasheet Summary
Customer Specific Device from ON Semiconductor Advance Information Single Ended PWM Controller Featuring QR Operation and Soft Frequency Foldback
Features
The TY72011AP2 bines 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 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...
