IRU3046CFTR Description

The IRU3046CFTR IC combines a Dual synchronous Buck controller and a linear regulator controller, providing a cost-effective, high-performance, and flexible solution for multi-output applications. The Dual synchronous controller can be configured as a 2-independent or 2-phase controller. In a 2-phase configuration, the IRU3046CFTR provides a programmable current sharing which is ideal when the output power exceeds any single input power budget. IRU3046 provides a separate adjustable output by driving a switch as a linear regulator.
