概览

MC33470 是一款可数字编程的开关稳压器，专为微处理器电源、稳压器模块和通用应用而设计，使用极少外部零件提供大功率调节输出电压。一个 5 位数字-模拟转换器定义直流输出电压。此产品还具有三个附加特性。首先是一对高速比较器，用于监控输出电压，加快电路针对负载电流变化的响应速度。第二个特性是一个软启动电路，用于在应用输入电源时以及从外部电路故障情况恢复时建立受控响应。第三个特性是两个输出驱动器，提供同步整流，实现最佳能效。此产品适用于需要准确性、能效和最佳调节性能的计算机、消费品和工业设备。

  • 5-Bit Digital-to-Analog Converter Allows Digital Control of Output Voltage
