ETA ETA1459
The ETA1459 is a wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2.5A of output current. Its output can be dynamically controlled by I2C interface. Therefore, ETA1459 is a much superior solution in comparison to other competitions in terms of efficiency and cost.| Part No. | ETA1459 |

DESCRIPTION
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, ETA1459 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. Cycle-by-cycle current limit provides output short-circuit protection and an input OVP function guards ETA1459 against possible input voltage surge. Overall, ETA1459 is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. ETA1459 is housed in a ESOP8 Package.FEATURES
