ETA1486 Datasheet | ETA

DESCRIPTION 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 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, 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 parison to other petitions 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. ETA1486 is available ESOP8 Packages.
