     CXSD62275是一款采用电流模脉宽调制（PWM）架构的降压型DC-DC变换器，可以提供1.2A的负载电流，具有很好的线性调整率和负载调整率。CXSD62275可以在4.5V～30V宽输入电压范围内稳定工作，通过外部分压电阻调节实现0.8V~15V的输出电压。CXSD62275具有周期性的峰值电流限制和过温等保护机制，以确保芯片工作的安全性。芯片在关断模式下的静态电流可低至1μA。 内部的软启动功能可以很好的抑制浪涌电流和输出电压的过冲。CXSD62275采用SOT23-6和TSOT23-6封装，并且通过少数量的标准外围器件实现变换器功能，有效的节省了应用空间。The CXSD62275 is current mode, step-down switching regulator capable of driving 1.2A continuous load with excellent line and load regulation. The CXSD62275 can operate with an input voltage range from 4.5V to 30V and the output can be externally set from 0.8V to 15V with a resistor divider. Fault protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 1μA of supply current. Internal soft-start minimizes the inrush current and the output overshoot. The CXSD62275 is available in SOT23-6 and TSOT23-6 packages.
