LT8609/A/B Synchronous Step-Down Regulators

Analog Devices Inc. LT8609/A/B Synchronous Step-Down Regulators are compact, high efficiency, high speed, and consume 1.7µA of non-switching quiescent current. The LT8609/A/B Regulators deliver 3A of continuous current. The devices offer a Burst Mode operation enabling high efficiency down to very low output currents while keeping the output ripple below 10mVP-P.
