AC/DC & isolated DC/DC switching regulators

Optimize power conversion with our comprehensive portfolio

We offer one of the world's largest comprehensive portfolio of high-performance AC/DC and isolated DC/DC controllers, converters and modules with the widest range of power topology options. Our easy-to-use devices help you innovate and differentiate your power supply design to deliver high-efficiency, high-power density and high-performance isolated power conversion.

Product portfolio

Flyback controllers

Our flyback controllers are typically used for power under 150 W. From low-cost applications to high power-density, our portfolio supports features such as valley switching, quasi-resonant, zero-voltage switching (ZVS) & active-clamp flyback (ACF).

Isolated DC/DC converters & modules

Our converters and modules provide higher integration and ease-of-use. We offer integrated MOSFET products for flyback, LLC, push-pull and Fly-Buck™, as well as integrated transformer isolated DC/DC modules.

Pulse-width modulation (PWM) controllers

Our PWM controllers are control ICs for switch-mode power supplies which support output powers from less than one watt to multiple kilowatts. Our portfolio of PWM controllers can be used in DC/DC, AC/DC and DC/AC circuits.

LLC controllers

Our LLC controllers offer zero-voltage switching that provides high efficiency, low component count and improved EMI performance in applications up to 1kW

Power-factor correction (PFC) controllers

Our PFC controllers can help meet standards like DoE Level-VI and EU CoC Tier-2 and include single-phase transition mode (TM) and continuous conduction mode (CCM) as well as interleaved TM and CCM controllers.

SR & load share controllers

Our synchronous rectifier (SR) and load share controllers enable higher efficiency for power supplies let you connect multiple independent power supplies in parallel.

Power trends

Power management is at the center of enabling the continued integration of electronics in our lives. For decades, TI has been at the forefront of developing new process, packaging and circuit-design technologies to deliver the best power devices for your design. Check out our featured AC/DC and isolated DC/DC controllers, converters and modules below, designed to help you address power density challenges. 

AC/DC & isolated DC/DC switching regulators for power density

The growing need to design efficient power supplies is met with our innovative controllers and converters portfolio of devices, designed to deliver more and waste less energy. These devices can improve light load performance while eliminating the need to switch off the PFC, which meets the industry’s growing pressure on performance, but does so while minimizing the number of external components.
