    The SY8970 is an integrated power management unit. It is designed to power a wide range of microcontrollers and solid-state drive applications. 

    The device includes a load switch, 3 buck converters using integrated power FETs and a low-dropout regulator (LDO). Each buck converter switches at 2 MHz, requiring three small components for operation. All regulators can be configured for a wide range of output voltages through the I2C interface. 

    The SY8970 is available in a Fan-out CSP3.2x4.2-48 package.
