DC-DC regulators boast small footprint
23 January 2008
Power Electronics / Power Management
Targeting the market for high density, high performance data centre and consumer applications, International Rectifier has introduced the SupIRBuck family of single output synchronous buck voltage regulators. The IR38xx SupIRBuck family of point-of-load (POL) voltage regulators integrates IR's HEXFET trench technology MOSFETs and a high performance synchronous buck control IC in a compact 5 mm by 6 mm Power QFN package, said to shrink the silicon footprint by 70% compared to discrete solutions, and offer between 8 and 10% higher full-load efficiency than competing monolithic ICs. Designed for four, seven and 12 A of output load current at 600 kHz switching frequency, the devices operate from a wide input voltage range of 2,5 V to 21 V, and provide output voltage as low as 0,6 V. Common features include pre-bias start up, hiccup current limit, thermal shutdown, and precise output voltage regulation. Optional features include tracking, programmable power good, and 300 kHz switching frequency to provide an additional two Amps of output current capability.
