ST’s monolithic switching regulators offer input-voltage capability up to 55 V, deliver output currents up to 4 A, with high switching frequency. This broad portfolio of ICs is composed of highly-specialized products to meet every market requirement: HV technology, together with high reliability and robustness for industrial and automotive applications, compactness, high efficiency at any load and a high level of performance for consumer and computer products.
These devices embed a full set of protection functions (overcurrent, overvoltage, over-temperature) to increase the MTBF and reduce the number of external components.
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.
