Sychronous Buck Power Block Offers Space Savings In POL Converters
International Rectifier introduced the iP1206, a fully optimized sychronous buck power block for telecom and networking equipment. It is the latest addition to the iPOWIR integrated power conversion stage product line, designed for two-phase single output applications up to 30A or dual independent outputs up to 15A. Both options use synchronized 180° 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.
