2A synchronous step-down DC/DC converter

ELM605DA

■General description

ELM605DA is low-input voltage and high-output current synchronous-buck PWM converter and integrates

with all required active components. Its' operating input voltage ranges from 2.5V to 6V and output voltage

ranges from Vin down to 0.8V. ELM605DA operates at a ﬁxed switching frequency of 1.0MHz. In addition, it

provides internal soft-start to reduce inrush-current, current-limit and thermal shutdown, preventing IC from

being damaged and improving design reliability. Open-drain power good monitors the output voltage.
