ELM611DA 2A 23V
high efficiency synchronous PWM step down DC/DC converter
■General description
ELM611DA is 350kHz 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 equ...
