General Description
The RY1303 is a 3-CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter. It integrates three synchronous buck regulators and can provide high efficiency output at light load and heavy load operation. The internal compensation architecture simplifies the application circuit design. Besides, the independent enable control makes the designer have the greatest flexibility to optimize timing for power sequencing purposes.
The RY1303 is available in a 20-pin QFN 3×3 package.
