General Description
The RY1228AD10 is a 2-channel PMU that includes dual high frequency, synchronous, rectified, step-down, switch-mode converters with internal power MOSFETs. Two inputs voltage range from 4.5V to 17V and two outputs with up to 2A current. ECOT control operation provides very fast transient response and easy loop design as well as very tight output regulation.
The RY1228AD10 requires a minimal number of readily available, external components and is available in an DFN10-3×3 package.
