10.1.2 Standby Power Reduction

Battery powered end equipments often have strict power budgets, in which there is a need to reduce current consumption. The TPS22976 significantly reduces system current consumption by disabling the supply voltage to subsystems in standby states. Alternatively, the TPS22976 reduces the leakage current overhead of the modules in standby mode as achieved in Figure 10-2. Note that standby power reduction can be achieved on either channel, as well as dual-channel operation.
