Infineon Technologies IRU3146CFTR is a highly integrated, dual-phase synchronous buck controller designed for efficient step-down DC-DC conversion. This device operates with a switching frequency of 300kHz and offers a maximum duty cycle of 85%, supporting applications requiring robust power delivery. Key control features include current limiting, enable functionality, frequency control, power good indication, and soft-start for optimized transient response. The IRU3146CFTR is packaged in a 28-TSSOP (0.173", 4.40mm Width) and is supplied on tape and reel (TR) for automated assembly. Its output configuration is positive, and it supports two output phases with a transistor driver output type. The operating voltage range is from 4.5V to 16V. This controller is suitable for use in power supplies for computing, industrial automation, and advanced consumer electronics.
