High-Vin, High-Efficiency Power Solution Using DC/DC  
Converter With DVFS

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.
