产品概述 返回TOP
CXSD6154是一款高效率,1.5MHz固定工作频率,电流模式PWM单片式降压稳压器,可以提供输出电压可 调品种和1.2V、1.8V等固定输出电压的品种。稳压器在无负载时的工作电流为350uA;当处于关断时, 工作电流降到1uA以下。输入工作电压范围为2.5V至6.5V,非常适合于单节锂离子电池或两至四节干电 池供电的电子产品。CXSD6154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,CXSD6154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。1.5MHz的开关频率,使得外围的电感和电容可以微型化。CXSD6154内置功率开关管和同步整流开 关,无需外接肖特基二极管。反馈端电压设置为0.6V,可使输出电压低至0.6V。使用小型SOT89-5L封装。
