2A, 20V, 550kHz, synchronous step-down DC/DC converter

ELM613DA

■General description

ELM613DA is 550KHz fixed frequency PWM synchronous step-down regulator. ELM613DA is operated from

4.75V to 20V, the generated output is adjustable from 0.923V to 18V, and the output current can be up to 2A.

The integrated two MOSFET switches is with turn on resistance of 0.085Ω. Current mode control provides fast

transient response and cycle-by-cycle over current protection. The shutdown current is 1μA typical. Adjustable

soft start prevents inrush current at turn on. ELM613DA is with thermal shutdown.
