ELM611DA
description
ELM611DA is 350k Hz fixed frequency PWM synchronous step-down regulator, whose input voltage can be set within the range from 4.75V to 23V and output one is adjustable within the range from 0.923V to 18V; maximum output current of ELM611DA can reach 2A. ELM611DA includes 2 switching MOSFETs whose ON resistance is 85mΩ. Current mode control of ELM611DA makes it possible to provide fast transient response and current protection of cycle-by-cycle. Shutdown current is Typ.1μA. Soft start is programmable by external capacitor during start and limits inrush current to the appropriate value. ELM611DA is equipped with thermal shutdown protection.
