AC/DC switching regulators
Browse by category
TI offers AC/DC power conversion products across diverse topologies and applications. Our switching regulators offer improved electrical characterisitics for enhanced efficiency across line and load conditions, meeting modern power supply requirements. TI's converters offer the highest level of integration and enable design simplicity by combining the controller and gallium nitride (GaN) power stage into a single product. Our application-specific controllers integrate gate drivers and use soft-switching controlalgorithms without integrated power transistor. While the general-purpose controllers offer more topology flexibility with drop-in or pin-to-pin replacements. From mobile adapters to electric vehicle chargers, smart TV to datacenter server supplies, and energy infrastructure, TI's AC/DC switching regulators enable breakthrough performance in energy-crititcal applications worldwide.
