Product overview
Description
STDES-65ACFADP is a 65W USB PD adaptor reference design showing high efficiency performance over the entire operation load range and across the universal mains input voltage range.
This reference design opens the path to a compact solution with planar transformer technology and offers a high peak efficiency (93.7%). It also meets CoC tier 2 and DoE Level 6 efficiency requirements for average efficiency.
The soft switching topology helps on the low switching losses. The low-quiescent current consumption makes it best in class no-load consumption.
ST-ONE digital controller implements a proprietary ZVS active clamp flyback with low RMS current that makes it achieves high performance. The secondary losses are minimized using the synchronous rectification digital control embedded in ST-ONE.
A higher efficiency is ensured thanks to the reduction of switching and conduction losses and to the elimination of reverse recovery loss thanks to the perfomance of MasterGaN2. You do not have to take care anymore of GaN driving complexity to enjoy the benefits of GaN technology thanks to the highly integrated MasterGaN IC, enhancing the application robustness and layout simplifications.
