The SY70202S is an SSD PMIC which is composed of 4 synchronous Buck regulators and 2 independent LDOs. The LDO1, and LDO2 can work on load switch mode and the Buck4 works on the LDO mode which are flexible configuration via GPIOx pins. 

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

The SY70202S is available in a CSP 2.5 × 2.45 - 36 package.
