65W Active Clamp Flyback
The SZ1130 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 ease-of-design of a simple flyback controller with all the benefits of an ACF design, including recycling of the flyback transformer leakage energy and clamping of the primary FET drain voltage. Employing Silanna's OptiMode™ digital control architecture, the SZ1130 adjusts the device's mode of operation on a cycle-by-cycle basis to maintain high efficiency, low EMI, and fast dynamic load regulation.
Unlike conventional ACF designs, tight tolerances of the clamp capacitor and leakage inductance values are not required for proper operation of the circuit. Moreover, a small 3.3nF clamp capacitor is sufficient to realize the benefits of ACF operation. The SZ1130 is well suited for high efficiency and high-power density AC/DC power adapters. The device is designed for up to 65 W output power, including USB PD and Quick Charge applications.
