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. On top of the integrated

internal synchronous rectifier that eliminates external

Schottky diode, ETA1486 also employs a proprietary control

scheme that switches the device into a power save mode

during light load, thereby extending the range of high

efficiency operation. Therefore, ETA1486 is a much superior

solution in compar***n to other competitions in terms of

efficiency and cost. Overall, ETA1486 is a highly efficient

and robust solution for DC-DC step-down applications that

requires wide input ranges.
