DC-DC Switching Controllers With External Switch

View All Parametrics

Controllers for a Wide-Range of Isolated and Non-Isolated Regulator Topologies

We offer a comprehensive portfolio of external power switch DC-DC controllers for a wide range of isolated and non-isolated converter topologies. Our easy-to-use and cost-effective Constant-On-Time (COT) or Pulse-Wide Modulation (PWM) controllers support efficient power supply designs.

If you are looking for a controller with an internal FET in a single package, we offer DC-DC switching converters and DC-DC switching modules to simplify your power circuit design.
