一.产品概述HnI嘉泰姆

   CXSD6219 CXSD6219B是一款非常通用的工作电压达18V，输出电流达2/2.5A，HnI嘉泰姆

能量转换效率达95%的高压同步降压转换器。脚位和外围应用与通用的MPS1482完HnI嘉泰姆

全相同。同时在MPS1482的基础上，增加了轻载高效功能，和输入OVP，使得HnI嘉泰姆

CXSD6219 CXSD6219B待机功耗从10mA量级降到了1mA，同时可以耐受高达HnI嘉泰姆

30V的高压脉冲。CXSD6219 CXSD6219B采用SOP8封装，可输出2A电流。而HnI嘉泰姆

CXSD6219 CXSD6219BB采用ESOP8封装，可输出2.5A电流。HnI嘉泰姆

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

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

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

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

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

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

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

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

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

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

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

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

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

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

CXSD6219 CXSD6219B is a highlyefficient and robust solution HnI嘉泰姆

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

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