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.

DC-DC switching regulatorThe 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.

New high-efficiency DC-DC converter with digital output voltage selection and power good pin pushes performance beyond the limits

A miniaturized step-down regulator that draws a quiescent current of only 500 nA, the ST1PS01 is specifically tailored for battery-powered and energy-harvesting applications as it ensures a highly efficient power conversion regardless of the input voltage source and output current being delivered:

  • an input voltage ranging from 1.8 to 5.5 V
  • a minimal set of external components thanks to the integrated power switch, synchronous rectifier, and the embedded compensation network
  • a high efficiency at any load level, 95% at 1 mA output load current

An evaluation board, (STEVAL-1PS01EJR) helps developers quickly understand how to take advantage of the ST1PS01’s high energy efficiency and feature integration.
