The MAX8698CEWO+T is a highly integrated Power Management IC (PMIC) designed specifically for Samsung mobile devices in a WLP-56 (Wafer-Level Package) package. It integrates multiple DC-DC buck converters for core voltage generation, LDO regulators for peripheral rails, a Li-Ion battery charger with USB/AC adapter input selection, and a boost converter for backlight or OLED supply. The battery charger uses a CC-CV (Constant Current-Constant Voltage) algorithm with programmable charge current up to 1.5A and termination at 4.35V. The buck converters operate at 2.4MHz to minimize inductor size. An I2C interface allows dynamic voltage scaling (DVS) for DVFS power optimization. The WLP-56 package provides a 3.5×3.5mm footprint, essential for smartphone space constraints. Power-on sequencing is configurable via I2C registers to meet SoC requirements.
