ETA1860E8A 钰泰DC-DC降压开关稳压器芯片

　　DESCRIPTION

　　ETA1860 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. During light load, ETA1860 goes into a PFM mode that saves switching loss achieving high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load.

　　ETA1860 is available in ESOP8 package.

　　APPLICATIONS

　　Non-solated Telecommunication Buck Regulator

　　Secondary High Voltage Post Regulator

　　Automotive Systems
