One trend that shows no size of ending is the move to smaller personal electronic devices. From smartphones to tablets, each successive generation is smaller and more powerful than the last. It ...

A popular variant of this clamping method is the active-clamp flyback (Figure 1). It replaces the passive RCD clamp with an active FET and a clamp capacitor. This configuration makes it possible to ...

Silanna Semiconductor has designed an active clamp fly-back controller to reduce the ... “SZ1131 provides the ease-of-design of a simple fly-back controller with all the benefits ... Electronics ...

Switching at 150-260 kHz, a 65-W passive clamp QRF can achieve a power density of around 11W/in. 3; the equivalent active clamp flyback design switching at 120-165 kHz can achieve around 14W/in. 3 ...
