 The CXSD6219 CXSD6219B is a wide input range, high-efficiency, Xrn嘉泰姆

DC-to-DC step-down switching regulator, capable of delivering up to Xrn嘉泰姆

2.5A of output current. Current mode PWM control allows the use ofXrn嘉泰姆

 small external components, such as ceramic input and output caps,Xrn嘉泰姆

 as well as small inductors, while still providing low output ripples. Xrn嘉泰姆

On top of the integrated internal synchronous rectifier that eliminatesXrn嘉泰姆

 external Schottky diode, CXSD6219 CXSD6219B also employs a Xrn嘉泰姆

proprietary control scheme that switches the device into a power Xrn嘉泰姆

save mode during light load, thereby extending the range of high Xrn嘉泰姆

efficiency operation. Therefore, CXSD6219 CXSD6219B is a muchXrn嘉泰姆

 superior solution in comparison to other competitions in terms of Xrn嘉泰姆

efficiency and cost. Cycle-by-cycle current limit provides output Xrn嘉泰姆

short-circuit protection and an input OVP function guards CXSD6219 Xrn嘉泰姆

CXSD6219B against possible input voltage surge. Overall, Xrn嘉泰姆

CXSD6219 CXSD6219B is a highlyefficient and robust solution Xrn嘉泰姆

for DC-DC step-down applications that requires wide input ranges.Xrn嘉泰姆

CXSD6219 CXSD6219B is housed in a ESOP8 Package. Xrn嘉泰姆
