Group Switch Tank Converter Products

YAGEO Group (KEMET, YAGEO, Pulse) Switch Tank Converter (STC) Products are high-efficiency, high-density converters designed for non-isolated DC-DC applications. These devices operate by replacing the large magnetics typically used in converter designs with stacking voltages using switches and capacitors. The STC products are strategically placed between the input and DC-DC converter stages of the YAGEO group's Digital Architecture Passive Components. As a solution, these STC products take advantage of advanced semiconductor technology to support power supplies.
