The SY70202U is an SSD PMIC composed of 4 synchronous Buck regulators and 2 independent LDOs. The LDO1, and LDO2 operates in load switch mode and the Buck4 operates in LDO mode, which can be configured via GPIOx pins. 

Other configurable options include output voltage, startup time, system level sequencing, sleep mode, deep sleep mode, and operating mode etc. Each channel provides a wide voltage range to support DVS (Dynamic Voltage Scaling) through I2C interface. The Buck converters are designed to use very small size inductors. 

The SY70202U is available in a BGA3.35×3.1-34 package.
