A DC-DC switching converter is used to locally supply any component or part of a system with the desired DC voltage and current. Depending on the application's relationship between the input and output voltage, engineers have to choose the best power topology – buck, boost, buck-boost or inverting, with or without synchronous rectification. Or they can decide to use an implementation based on monolithic ICs or with discrete power switches and controllers – or even an advanced digital implementation. Whatever their choice, the right semiconductor products are key to meeting their specific efficiency and size design targets.

ST’s broad product portfolio includes highly-integrated DC-DC converters, power MOSFETs and rectifiers, protection ICs, linear voltage regulators, and specifically designed digital controllers and STM32 microcontrollers. We also provide a comprehensive range of hardware and software evaluation and development tools including our eDesignSuite that helps engineers design high-efficiency DC to DC converters.
