ST’s monolithic DC-DC switching regulators offer input-voltage capability up to 61 V, buck converters able to deliver output currents up to 6 A, and high switching frequency up to 2.3MHz.
broad portfolio of ICs is composed of highly-specialized products to meet every market requirement and power management needs: high voltage technology, together with high reliability and robustness for industrial and automotive, compactness and high efficiency for consumer applications.
These switched-mode power supply devices embed a full set of protection functions (overcurrent, overvoltage, over-temperature) to increase the MTBF and reduce the number of external components needed for power conversion. There are multiple package options, all offering compactness and high thermal performances to fit different applications.
ST also has a unique and fully isolated, resonant, single-stage direct conversion from 48 V straight to the Point-of-Load (PoL), CPU/DDR in full compliance to Intel VR13 and VR12.5 specifications, and a fully scalable solution able to manage up to 6 interleaved cells with dynamic cell shedding and pulse skipping.

ST’s new L7983 is a compact synchronous buck converter able to satisfy noise-sensitive applications and maximize efficiency at light load thanks to its Low-noise and Low-consumption modes.
With a wide input-voltage range, the L7983 can operate from 12 and 24 V industrial buses with wide safety margins. It is also suitable for battery-powered applications, industrial fail-safe systems, decentralized intelligent nodes, appliances, robotics and precision-sensing applications that leverage the easy-to-use Low-noise mode.
Power supply and converter solution evaluation boards based on the L7983 are also available
