The core-voltage requirements of these newest 3-GHz DSPs typically range from 0.9 V to 1.1 V but require tolerance levels of ±3%. In addi- tion, large current transients make the task of delivering reliable processor power even more challenging. To meet these challenges, TI’s T2 plug-in power products offer extremely fast transient response. These compact and cost-effective devices have been designed to deliver reliable processor core power that reduces bulk capacitance.
