Power conversion device for POL buck converters

The iP1206 from International Rectifier 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. Features include a switching frequency up to 600 kHz per channel, loss-less current limit, over-voltage and over-temperature protection, pre-bias start up, external synchronization, output voltage tracking and sequencing. Available design tools include a web-enabled iP1206 Spice circuit simulation, and the IRDCiP1206-B, a 15A per channel, dual output, synchronous buck converter reference design.
