A buck or step-down topology is used in DC-DC switching converters where the output voltage is lower than the input with or without input-output isolation.
We have a large offer of buck regulators - with integrated power switches – and controllers providing a wide range of features including soft start to minimize inrush current and power-good to enable power-up sequencing. Programmable devices are also available to help design buck converters fine-tuned for specific EMI, EMC, efficiency and power density targets and use cases.
We have also developed an isolated, single-stage direct 48 V to the Point-of-Load (PoL) resonant, conversion solution for use in CPUs or DDR memories compliant with Intel VR13 and VR12.5 specifications. ST also offers a fully scalable solution for up to 6 interleaved cells with dynamic cell shedding and pulse skipping features.
In addition, we have a comprehensive set of evaluation and development tools as well as reference designs to help compress time to market.
