Description
The SZ1131 is an Active Clamp Flyback (ACF) PWM Controller that integrates an adaptive digital PWM controller and the following Ultra High-Voltage (UHV) components: active clamp FET, active clamp driver and a start-up regulator.The device provides the ease-of-design of a simple flyback controller with all the benefits of an ACF design, including recycling of the leakage inductance energy of the flyback transformer and limiting the primary FET drain voltage spike during the turn-off events. Employing Silanna’s OptiModeTM digital control architecture, the SZ1131adjusts its mode of operation on a cycle-by-cycle basis to maintain high efficiency, low EMI, fast dynamic load regulation and other key power supply parameters in response to varying line voltage and load.
