To achieve higher power levels, these initiatives require efficiencies of 87% and above.due to standardflybacktype (flyback) and dual switchPositiveThese high efficiency stages are not supported by traditional power topologies such assoft switchreplaced by resonant and quasi-resonant topologies. working […]

IBIS Modeling – Part 1: Why IBIS Modeling is Critical to Design Success

“This paper presents an IBIS Model with a quality level of 2a. After passing the resolver test, the model is simulated, including RLC package parasitics and imposed loads. The load is usually the timing test load value found in the data sheet to characterize the I/O buffer. Similarly, the design schematic of the device will be simulated with the same […]

Domestic ion implanter signed a big order! Wanye Enterprise wants to be a “climber” of domestic equipment

In semiconductor equipment, if the lithography machine is the Mariana Trench, and there are very few people who go to the bottom, then the ion implanter is Mount Everest, and there are very few people who can conquer it. After the founding of New China, the height of Mount Everest was measured by the British, the French, and even by […]
