General 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 ponents, 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, ETA1485 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.
