IR Presents iP1001 Synchronous Buck Converter

International Rectifier Corp. (IR, El Segundo, CA) introduced the iP1001 iPOWIR device, a 20A, single-phase synchronous buck converter "building block" that integrates power semiconductors and layout-critical passive components. The new iPOWIR device replaces up to 20 discrete components, cutting component count by 90 percent and providing up to five percent improvement in efficiency.

The iP1001 is rated at 20A maximum output current at a board temperature of up to 96 degrees C for a 5V to 16V input. The new device has digital-to-analog converter selectable output voltages between 0.925V and 2.0V to within ±1 percent regulation. Output voltages up to 3.3V can be achieved with simple external circuitry and can be configured to operate at input voltages as low as 2.5V. Housed in a 14mm x 14mm x 3mm ball-grid array package, the iP1001 reduces footprint by up to 40 percent.

The iP1001 building block is designed for single-phase, non-isolated dc/dc converters for computing, network, telecommunications and data communications equipment, including switchers and routers. It is suitable for CPUs, network processing units, ASICs, and peripheral or auxiliary rail applications up to 20A.

Samples are now available with volume production in January 2002. Pricing is $14.44 each in 10,000-unit quantities.
