RY9121 Overview
The RY9121 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very pact solution to provide a 2A continuous output current over a wide input supply range, with excellent load and line regulation. ECOT control operation provides very fast transient response and easy loop design as well as very tight output regulation.
