Highly efficient voltage regulators

18 March 2009 Power Electronics / Power Management

International Rectifier has introduced its second generation of SupIRBuck integrated point-of-load voltage regulators for energy-efficient telecom, consumer, set-top box, high performance server and storage applications. The Gen2 SupIRBuck family features IR’s latest advances in control IC, MOSFET and package integration technologies to deliver 4 A, 8 A and 12 A output current with high efficiency over the entire load range. While optimised for 12 V input voltage, high efficiencies are also achieved in applications with 9,6 V, 5 V or 3,3 V input voltages. The new devices offer a high switching frequency up to 1,5 MHz to allow the use of smaller inductors and fewer output capacitors. The devices’ thermal properties deliver full current rating with no air flow and without a heatsink, and allow back-side mounting on a mother­board to provide additional space savings.
