DC-DC Switching Converters, Controllers and Modules

Wide Selection of External Switches, Integrated Switches and Highly Integrated Modules

You need high-performance DC-DC power control and conversion solutions that support a wide range of features and functions to maximize efficiency in your power supply circuits. However, choosing the right product can be difficult because many manufacturers lack diverse package options, product features and support. Fortunately, with our easy-to-use, cost-effective switching controllers, converters and modules, you can design with confidence by spending less time worrying about powering your design and more time adding value to it.

DC-DC Switching Controllers

Controllers With External Power Switching

We offer a comprehensive portfolio of high-performance isolated and non-isolated analog DC-DC controllers. Our easy-to-use and cost-effective Constant On-Time (COT) controllers allow you to design feature-rich, flexible and high-performance DC-DC switching power supplies.

We offer the following products:

  • Isolated DC-DC controllers
  • Non-isolated DC-DC buck controllers
  • Driverless DC-DC controllers
  • Boost controllers with external power switches

DC-DC Switching Converters

Controllers With Integrated Power Switching

Our DC-DC Switching Converters are designed for efficient power designs, ranging from powering core supplies needing I2C communication and dynamic voltage scaling capabilities to battery-operated systems with a low-quiescent current requirement.

We offer the following products:

DC-DC Switching Power Modules

Integrated Controllers, Power Switches and Inductors

Our highly integrated DC-DC power modules contain a controller, power switches and the necessary passive components—all of which are fully tested and pre-characterized for EMI and DC performance—to offer a complete switching power supply solution.

As turnkey solutions that speed your time to market, these devices contain optimized pinout for easy layout and assembly.

Integrated Power Management for Embedded Processors and Subsystems With Multiple Power Rails

Our Power Management ICs (PMICs) are excellent for embedded and application processors and other components in complex systems that require multiple power rails and multiple power domains. Using discrete devices for power management in these types of systems can be costly. However, PMICs integrate multiple voltage regulators and control circuits into a single chip to implement complete power supply solutions. They reduce component count and board space while easily and cost effectively managing system power.

Advantages of Designing With PMICs

  • Simplifies power management in complex embedded systems 
  • Provides power supplies for processing systems
  • Optimizes power consumption and extends battery life
  • Helps control complex power systems
  • Reduces circuit board space
  • Reduces time to market and risk 
  • Reduces engineering and sourcing effort
