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

SGM61012S 与 SGM61022S 是两款同步降压转换器，高效率并且高频，具备从 2.3V 至 5.5V 的宽泛输入电压范围，并提供宽输出电流范围，优化设计以适应紧凑型解决方案。在高负载状态下，这些转换器采用 PWM（脉冲宽度调制）模式工作，而在低负载状态下则自动转换至省电模式（PSM），以此维持其高效性能。\n通过配置 MODE 引脚，可以激活深度睡眠模式（DSM）。在此模式下，器件以极低的静态电流运行，即便在极低负载条件下也能保持高效能。这一特性有效降低了待机电流，有助于延长电池供电设备的待机时长。为了适应各种系统电源轨道的需求，内部的环路补偿设计支持使用超过 100μF 的输出电 • 输入电压范围：2.3V 至 5.5V\n• 输出电流：• SGM61012S：1.2A\n• SGM61022S：2A;
