一.产品概述kdj嘉泰姆


  The CXSD62018 is a wide input range, high-efficiency, DC-to-DC step-down kdj嘉泰姆

switching regulator, capable of delivering up to 2.5A of output current. Itskdj嘉泰姆

output can be dynamically controlled by I 2 C interface. Current mode PWM kdj嘉泰姆

control allows the use of small external components, such as ceramic input kdj嘉泰姆

and output caps, as well as small inductors, while still providing low kdj嘉泰姆

output ripples. On top of the integrated internal synchronous rectifier kdj嘉泰姆

that eliminates external Schottky diode, CXSD62018 also employs a proprietary kdj嘉泰姆

control scheme that switches the device into a power save mode during light kdj嘉泰姆

load, thereby extending the range of high efficiency operation. Therefore, kdj嘉泰姆

CXSD62018 is a much superior solution in comparison to other competitions in kdj嘉泰姆

terms of efficiency and cost. Cycle-by-cycle current limit provides output kdj嘉泰姆

short-circuit protection and an input OVP function guards CXSD62018 against kdj嘉泰姆

possible input voltage surge. Overall, CXSD62018 is a highly efficient and kdj嘉泰姆

robust solution for DC-DC step-down applications that requires wide input kdj嘉泰姆

ranges. ECXSD62018is housed in anESOP8 Package.kdj嘉泰姆
