High-Vin, High-Efficiency Power Solution Using DC/DC

Converter With DVFS

Ambreesh Tripathi .......................................................................... PMP - DC/DC Low-Power Converters

ABSTRACT

This reference design is intended for users designing with the TMS320C6742, TMS320C6746,

TMS320C6748, or OMAP-L138 processor. Using sequenced power supplies, this reference design

describes a system having a 12-V input voltage and a high-efficiency dc/dc converter with integrated FETs

and dynamic voltage and frequency scaling (DVFS) for a small, simple design.

Sequenced power supply architectures are becoming commonplace in high-performance microprocessor

and digital signal processor (DSP) systems. To save power and increase processing speeds, processor

cores have smaller geometry cells and require lower supply voltages than the system bus voltages. Power

management in these systems requires special attention. This application report addresses these topics

and suggests solutions for output voltage sequencing.
