ETA1483
DESCRIPTION
The ETA1483 is a wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2A 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, ETA1483 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, ETA1483 is a much superior solution in parison to other petitions in terms of efficiency and cost. Cycle-by-cycle current limit provides output shortcircuit protection and an input OVP function guards ETA1483 against possible input voltage surge. Overall, ETA1483 is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. ETA1483 is...
