ELM605DA数据手册ELM-Tech中文资料规格书

描述 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.
