Why is this compelling?

• Ease of design; Simple layout – reference design not necessary

• Lower component count

• Lower EMI, conductive noise

• Higher power density – PCB area is a premium

• Higher efficiency – shorter interconnection, lower parasitics

• Better thermal transfer

• Eliminates the pain point (L selection and mounting)

Capacitor Integration

• Capacitors

– Smaller/denser capacitors for PSiP:

• NOVACAP, a Dover Company introduces a new line of high-capacitance multilayer ceramic capacitors (MLCCs) that combine higher volumetric capacitance per given board area with lower equivalent series resistance (ESR) than alternative solutions.

– Integration continues to be further off (DRAM derivatives)

– Enablers:

• Quantum jump in switching frequency.

Future Trends

• More isolated dc-dc converters.

• Off-line isolated high voltage ac-dc converters.

• Maybe integrated inductor and the PwrSoC.

• Follow the Power IC, PMU and Power PMU developments.

• Higher power train functionality

In the coming year or two we will see
