step down DC/DC converter

ELM611DA

synchronous PWM

high efﬁciency

■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 equipped with thermal

shutdown protection.
