Analog Devices Inc. LT8612 Synchronous Step-Down Regulators
Analog Devices Inc. LT8612 Synchronous Step-Down Regulators are compact, high-efficiency, high-speed, monolithic step-down switching regulators. The LT8612 consumes only 3μA of quiescent current and includes top and bottom power switches with all necessary circuitry. This minimizes the need for external components. Analog Devices Inc. LT8612 Regulators feature a low ripple Burst Mode operation, enabling high efficiency down to very low output currents while keeping the output ripple below 10mVP-P.
