International Rectifier has expanded its SupIRBuck family of integrated point-of-load (POL) voltage regulators. The new IR347x and IR386x devices for energy-efficient computing and consumer applications feature hysteretic constant on-time (COT) modulators with adaptive dead-time control to achieve high light- and full-load efficiency.
The devices, which integrate a high-performance controller with optimised power MOSFETs in a slim 4 x 5 mm or 5 x 6 mm PQFN package, are designed with a 0,5 V, 1% accurate internal reference voltage, allowing very low and precise output voltage programmability. The new products offer a set of features including over-temperature protection, thermally compensated over-current protection, over- and under-voltage protection, pre-bias startup, power good output and enable input with voltage monitoring capability.
The IR347x family is capable of up to 27 V input voltage and is available in a 4 x 5 mm and 5 x 6 mm PQFN package to cover a broad range of loads from 6 A to 15 A, making it scalable to meet price and performance requirements. These options and high light load efficiency make the IR347x a suitable choice for power conversion in mobile applications such as laptop computers. Other applications include light industrial and battery-based applications that operate from 24 V rails.
The IR3863 and IR3865, available in a 4 x 5 mm PQFN package, are optimised for 12 V input applications, such as laptop computers, including those designed with the recently announced second generation Intel Core processor family. In addition, the new SupIRBuck devices are well suited to consumer DC-DC applications including printers, LCD TVs and game consoles.
