Building Block Shrinks Buck Converters
An addition to International Rectifier’s iPOWIR integrated power conversion stage product line, the iP1206 is designed for two-phase single-output buck converter applications up to 30 A or dual independent outputs up to 15 A. The iP1206 consists of a full-function PWM control IC combined with an optimized power stage to achieve high power density.
Both the single- and dual-output options use synchronized 180 degree out-of-phase operation, reducing input current ripple and input voltage ripple. Other features include a switching frequency up to 600 kHz per channel, lossless current limit, overvoltage and overtemperature protection, pre-bias start up, external synchronization, output voltage tracking and sequencing.
