International Rectifier’s iPOWIR™’s Full Function Power Stage Plus Control IC Reduces Space and Simplifies Design Of High Efficiency POL Buck Converters

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the iP1206, a fully optimized solution for synchronous buck applications including telecom and networking equipment.

The iP1206 is the latest addition to the iPOWIR™ integrated power conversion stage product line, designed for two-phase single output applications up to 30 amps or dual independent outputs up to 15 amps. Both options utilize synchronized 180 degree out-of-phase operation, reducing input current ripple and input voltage ripple. The device is comprised of an optimized power stage and a full function PWM Control IC to achieve high power density.

“As with all iPOWIR products, the iP1206 is simple to design and easy to replicate across a wide range of voltage and current rails because all of the critical components are integrated and only a few external passive components are required for a complete POL solution,” said Tim McDonald, vice president of IR’s iPOWIR product line.

Features include a switching frequency up to 600kHz per channel, loss-less current limit, over-voltage and over-temperature protection, pre-bias start up, external synchronization, output voltage tracking and sequencing.
