4-8. Load Switch IC
Download "Chapter IV : Local Power Supply ICs" (PDF:770KB)
The load switch IC is connected between the power supply and the load (IC or LSI). It is a power management IC that reduces power consumption by controlling on/off of power supply lines supplied to ICs and LSIs depending on the operating mode of the system. A similar switch can be configured with a mechanical relay or a discrete (MOSFET), but the load switch IC has low power consumption and various protection functions built in, so that improvement of system reliability can be expected.
