1.2A/2A High-Efficiency Buck Converters with AHP-COT Mode

SGM61012S 和 SGM61022S 是两款高效的高频同步降压转换器，它们的输入电压范围覆盖从 2.3V 至 5.5V，并且拥有宽输出电流范围，专为紧凑型解决方案进行了优化设计。这些转换器在重载条件下以 PWM（脉冲宽度调制）模式运行，而在轻载条件下则会自动切换到省电模式（PSM），以保持高效率。\n通过设置 MODE 引脚，可以启用深度睡眠模式（DSM）。在这种模式下，器件以超低静态电流运行，即使在极低负载下也能维持高效率。这一特性有助于将待机电流降至最低，从而延长电池供电应用的待机时间。为了满足不同系统电源轨的要求，内部环路补偿设计允许使用容量超过 100μF 的输出电容。\n此外， • 输入电压范围：2.3V 至 5.5V\n• 输出电流：• SGM61012S：1.2A\n• SGM61022S：2A;
