ELM613DA 2A, 20V, 550kHz, synchronous step-down DC/DC converter ■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. ■Features • Programmable soft start • Short circuit protection • Thermal shutdown protection • Input voltage : 4.75V to 20V • Output voltage : 0.
