2 Proposed Solution

To provide flexibility and scalability in designing the VCCINT_VCU power rail for a wide variety of performance requirements, this technical note discusses solutions based on pin-to-pin compatible families of products able to deliver output currents ranging from 1/2-A up to 4-A, which can be selected and easily substituted according to the needs of the system, even at a late point in the design process.

The following sections concentrate on describing two highly efficient, solution-size optimized DC/DC converter families with focus on improving light load efficiency and transient response speed as shown in Section 2.1, or controlling and/or filtering out switching noise as shown in Section 2.2.
