    CXSD62289A是一款同步电流模降压型DC-DC变换器，可以提供高达3A的负载电流，具有很好的线性和负载调整率，轻负载时跳跃周期工作以提高效率。该变换器可以在4.5V～30V的宽输入电压范围内稳定工作，通过外部反馈电阻可方便地将输出电压设置为0.925V~20V。CXSD62289A具有过温功能，还可以在每个周期进行峰值电流限制，以确保芯片的可靠性。关断时静态电流可达1μA以下。所具有的可编程软启动功能可以有效减小启动时的输入浪涌电流和输出过冲。CXSD62289A仅需少量的外围器件即可实现变换器功能。The CXSD62289A is a synchronous current mode buck regulator capable of driving 3A continuous load current with excellent line and load regulation. The CXSD62289A can operate with an input range 4.5V to 30V and the output can be externally set from 0.925V to 20V with a resistor divider. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 1μA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. Automatic pulse skipping mode operation increase efficiency at light loads. The CXSD62289A require a minimum number of external components.
