Power Block facilitates design of POL buck converters.

Press Release Summary:

Comprised of power stage and full function PWM Control IC, iPOWIR(TM) iP1206 suits 2-phase single output applications up to 30 A or dual independent outputs up to 15 A. Both options utilize synchronized 180° out-of-phase operation, minimizing input current ripple and input voltage ripple. Housed in LGA package, Model iP1206 includes switching frequency up to 600 kHz/channel, over-voltage and over-temperature protection, pre-bias start up, and output voltage tracking and sequencing.

Original Press Release:

International Rectifier's iPOWIR(TM) Building Block 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(TM) 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.
