AC/DC switching regulators

Achieve higher power density with TI's AC/DC products, leveraging options from highly integrated GaN devices to flexible PWM controllers

parametric-filterView all products
TI offers AC/DC power conversion products across diverse topologies and applications. Our new switching regulators offer improved electrical characterisitics for 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. Without integrating power transistors, the application-specific controllers integrate gate drivers and use soft-switching control law like converters. And 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, energy infrastructure, and more, TI's AC/DC switching regulators enable breakthrough performance in energy-crititcal applications worldwide.
