DC DC Switching Controllers

DC-DC switching controllers are power management ICs used to control external power switches for efficient voltage conversion. They support buck, boost, buck-boost, flyback, and other switching topologies, and are commonly used in power supplies, industrial equipment, automotive electronics, communication systems, servers, battery-powered devices, and embedded applications.

TomatoElec is an independent electronic components distributor supplying DC-DC switching controller ICs from mainstream manufacturers such as Texas Instruments, Analog Devices, STMicroelectronics, onsemi, Infineon, Microchip, Renesas, NXP, Diodes Incorporated, and Monolithic Power Systems. Customers can check inventory, price, package, specifications, parameters and PDF datasheets in the product list below, and submit a BOM or RFQ for DC-DC switching controller sourcing support.
