The SY8600 is a high efficiency PMIC with 5-channel synchronous Buck converters and 2-channel LDOs. It is a single chip total power solution for SSD system.

The output voltage of channel3 and channel4 are controlled by the processor using the I2C interface. It therefore supports DVS (dynamic voltage scaling) function. The SY8600 can generate an open-drain reset output for the processor with certain delay time.

The SY8600 operates over a wide input voltage range from 2.8V to 5.5V. It is available in CSP3.23×3.23-52 package.
