ETA1485中文资料18V/3A高压同步降压转换器数据手册ETA规格书

描述 Description

The ETA1485 is a wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. Current mode PWM control allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples.
