三通道、单片式开关稳压器

LT®1941 是一款具内部电源开关的三通道、电流模式 DC/DC 转换器。其中的两个稳压器是具有 3A 和 2A 电源开关的降压型转换器。第三个稳压器可被配置为一个升压、负输出或 SEPIC 型转换器，并具有一个 1.5A 电源开关。所有三个转换器均被同步至一个 1.1MHz 振荡器。两个降压型转换器反相运行，从而减小了输入纹波电流。输出电压由外部电阻分压器来设定，而且每个稳压器都具有独立的停机和软起动电路。当其输出处于调节状态时，每个稳压器将产生一个电源良好信号，从而简化了电源排序以及与微控制器和 DSP 的连接。 \n\n 高开关频率通过允许使用小型电感器和陶瓷电容器提供了多个 • 宽输入范围：3.5V 至 25V \n\n• 具内部电源开关的 3 个开关稳压器：3A 降压型、2A 降压型、1.5A 负输出/升压型 \n\n• 反相开关操作减小了纹波 \n\n• 独立停机/软起动引脚 \n\n• 独立电源良好指示器简化了电源排序 \n\n• 输入电压电源良好指示器负责监视输入电源 \n\n• 采用小型电感器和陶瓷电容器 \n\n• 1.1MHz 恒定开关频率 \n\n•  耐热性能增强型 28 引脚 TSSOP 封装;
