The SY70202K is an integrated power management unit. It is designed to power a wide range of microcontrollers and solid-state drive applications. The SY70202K includes 4 buck converters with integrated power FETs and 2 low-dropout regulators (LDOs). The Buck1, LDO1, and LDO2 can also be configured as load switch. The PMIC supports a variety of default configurations. It is programmed at the factory with a default configuration. 

The SY70202K supports combination of multiple configurations, including output voltage, startup time, system level sequencing, sleep modes, deep sleep modes, and operating modes etc. Each of the regulators can be configured for a wide range of output voltages through the I2C interface. Each buck converter requires only three small components to operate at switching frequency of 2MHz. All regulators can be configured for a wide range of output voltages through the I2C interface. 

The SY70202K is available in a BGA3.35×3.1-34 package.
