ETA1663FSG 钰泰18V4A高效同步降压转换器

　　DESCRIPTION

　　ETA1663 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 4A of output current.

　　It adopts an Adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load. The adaptive COT control also maintains a constant switching frequency across line and load. An OVP function protects the lC itself and its downstream system against input voltage surges. Short-circuit and thermal-overload protection improves design reliability.

　　ETA1663 is available in a tiny SOT563 package.
