    The SY70201 is a Multi-channel PMIC which is composed of 4 synchronous Buck regulators, 1 LSW and 1 synchronous Boost regulator, 1 reset output and 1 reset enable output.

    All channels of regulators support PFM mode for light load efficiency. Each channel provides DVS (Dynamic Voltage Scaling), forced discharge, power good indicator, as well as power off mode by I2C interface. The PMIC are designed to use very small size inductors and support to control the special power-up sequence with soft-start and delay time. 

    The SY70201 is available in a compact QFN55-36 package.
