ETA1486
4A, 18V High Efficiency Synchronous Step-Down Converter
The ETA1486 is a wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 4A 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.
