ABSTRACT  
This reference design helps those desiring to design-in the TMS320C6742, TMS320C6746,  
TMS320C6748, and OMAP-L138. This design, employing sequenced power supplies, describes a system  
with an input voltage of 3.3 V, and uses LDOs for a small, simple system.  
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.
