It integrates four synchronous buck regulators and can provide high efficiency output at light load and heavy load operation. The internal pensation 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 RY1314 is available in a 24 pin QFN 4×4 package.
