IR Intros iPOWIR iP1203 Synchronous Buck Converter

International Rectifier Corp. (IR, El Segundo, CA) introduced the new iPOWIR™ iP1203, a fully optimized, full-function, 15 A single-output, synchronous buck converter device that achieves over 90% efficiency at full load. The iP1203 is a flexible solution that addresses requirements from 5.5 Vin to 13.2 Vin and 0.8 Vout to 8 Vout, maintaining a full load capability of 15 A.

The new power building block is designed to simplify dc-dc point-of-load (POL) converters for network processor units and ASIC power rails within networking and telecommunications systems. The iP1203 is suitable for use in two-stage distributed power architectures being fed from either a regulated isolated brick or an unregulated dc bus converter.

The iP1203 addresses important networking and telecommunications power system requirements such as hiccup over-current, over-temperature and over-voltage protection; external synchronization; and power-good and soft-start. The building block is housed in a land grid array (LGA) package measuring 9 mm x 9 mm x 2.3 mm. The iP1203 uses thermally enhanced mold compound, enabling dual-sided cooling capability and low junction-to-case and junction-to-PCB thermal resistance for maximum current handling.

The new iP1203 in the LGA package is available immediately. The iP1203TR is supplied in 1,000 pieces per tape-and-reel package. Pricing is $5.75 each in 1,000-unit quantities. Prices are subject to change.
