DESCRIPTION
The APU3046 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 2-independent or 2-phase controller. In 2-phase configuration, the APU3046 provides a programmable current sharing which is ideal when the output power exceeds any single input power budget.
