Today's mobile devices, such as smartphones and tablet PCs, are continuously trying to lower their power envelope by deploying the best power management ICs (PMICs).
Development of Samsung's PMIC products is in tandem and is tightly coupled with our AP solutions, and is hailed for meeting most of the power supply requirements for handheld devices.
Samsung S5M8763 PMIC, in particular, is designed to supply the power needed by its application processors (APs), including the Exynos 3110, as well peripheral components in today's leading edge smartphones, as shown in Figure 1.

The main PMIC is optimized for the power, voltage sequencing and control requirements of the AP. For this purpose, it contains buck converters, a linear LDO regulator, a real time clock, a primary battery charger along with a backup battery charger, a manual reset facility, and two buffered 32.768 kHz oscillators.
Samsung tries to integrate as many blocks as possible into its main PMIC to achieve both cost and size savings, as shown in Figure 2.
