CXSD61046 wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of deli

The CXSD61046 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 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, CXSD61046 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, CXSD61046 is a much superior solution in comparison to other competitions in terms of efficiency and cost. Cycle-by-cycle current limit provides output short-circuit protection and an input OVP function guards CXSD61046 against possible input voltage surge. Overall, CXSD61046 is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. HCXSD61046 is housed in a SOP8 Package
