产品概述 返回TOP
CXSD6155 CXSD6155A是一款高效率、1.2MHz固定工作频率、电流模式PWM单片式降压稳压器,非常适合于由单节锂 离子电池供电,峰值工作电流可达2A的条件下仍要求效率达到90%以上的便携式产品。CXSD6155 CXSD6155A在低压 差工作模式下,占空比可达100%,延长了便携式设备的电池寿命。在输出负载变低时,CXSD6155 CXSD6155A用脉冲跳跃模式工作,保证了低的输出纹波电压,有利于对噪声敏感的应用环境。输入工作电压范围为2.5V至 6.0V,输出电流可达2A,输出电压可低至0.6V。1.2MHz的开关频率,使外围元件可以小型化,内部补 偿设计使得用小电感量电感(可减小体积)也足以保持高效率工作。CXSD6155 CXSD6155A有3mmx3mm10引脚DFNWB 和MSOP两种封装形式,工作温度范围-40℃~+85℃
