LISTED UNDER:

IR SupIRBuckComing in a 5 mm × 6 mm × 0.9 mm Power QFN package, International Rectifier’s SupIRBuck family point-of-load (POL) DC/DC voltage regulators integrates synchronous buck control ICs and benchmark HEXFET trench technology MOSFETs. The components exhibit 4 A, 7 A, or 12 A of output current load, input voltage range from 2.5 V to 21 V, and an output range from 0.6 V to 12 V. The regulators present a fixed switching frequency of 600 kHz, pre-bias start up, hiccup current limit, thermal shutdown, output voltage regulation, programmable soft start with enable, and programmable overcurrent protection. Optional offerings include a 300 kHz switching frequency, DDR memory tracking, and programmable power good.
