The SY5882 is a power management IC (PMIC) designed for notebook, desktop, and embedded computing platforms. There are three DCDC converters and two linear regulators integrated into the SY5882, which can minimize the need for external components so that it can ease the layout in a constrained PCB area. The DCDC converters are of high accuracy, high efficiency, and high flexibility. Two LDOs provide power rails for peripherals and pull-up resistors.
The SY5882 provides protection for a device when a fault occurs, such as overcurrent, output overvoltage, output undervoltage, short circuit, input overvoltage, and over temperature.
The SY5882 is a halogen- and lead-free device, compliant with RoHS. The package is QFN3x3-20.
