Moving on to even more highly integrated devices and offerings from Texas Instruments, there are devices dedicated to OMAP processors inside our TPS65 family. As can be seen, the OMAP processor brings many, many features with it, but also requires a larger power management solution. The TPS65 devices deliver the dedicated power management that the OMAP devices require. One of the features to consider is on the bottom right, the I²C interface which can help you reduce the amount of energy which you draw from the battery. For example, when the processor is running at high performance and it is driving multiple applications. This uses a large amount of energy coming from the battery. Even if not all the applications are running the processor is still requiring energy. With this usage, leakage and etc., it is drawing more energy from the battery than really needed. There are many types of losses which can be avoided. A way to do this is feed a signal from the processor back to the power management, the TPS65 devices can then regulate the voltage down and reduce overall power consumption to save energy needed from the battery. The drawback of a highly integrated power management unit is that power management is just at one spot. If it is necessary to distribute the power management, there is a risk of EMI due to transmitting the power across the PCB. In this case, it may be better for the additional application to have a single output linear regulator or DC/DC regulator.
