高效率、四路输出、主电源控制器，用于笔记本电脑

MAX8744A/MAX8745A是一款双路、降压型、带同步整流的开关电源(SMPS)控制器，非常适合电池供电系统，能够产生5V/3.3V主电源。在最低输入电压至26V最高输入电压范围内，器件保持固定工作频率和交错式工作，使输入纹波电流最小。经过优化的40/60交错工作方式能够在输入电压低至8.3V时不发生占空比重叠；而180°错相工作方式在输入电压降至10V时，即发生占空比重叠。\n 输出电流检测提供峰值限流保护，可以使用精密的检流电阻或利用电感的DCR进行无损耗电流检测。低噪声模式能够在轻载下保持较高效率，并使开关频率在音频范围以外。\n 内部5V、100mA线性稳压器为MAX8744A/ \n• 固定频率、电流控制模式控制 \n• 40/60交错式工作 \n• 内部BST开关 \n• 内部5V、100mA线性稳压器 \n• 辅助线性稳压驱动器(提供12V或最低可调至1V) \n• Dual Mode™反馈—3.3V/5V固定输出或可调输出 \n• 200kHz/300kHz/500kHz开关频率 \n• 欠压和热故障保护 \n• 过压保护(仅MAX8744A) \n• 输入范围：6V至26V \n• 2V ±0.75%基准电压输出 \n• 独立的使能输入和电源就绪输出 \n• 软启动和软关断(电压线性上升/下降) \n• 关断电流：8µA (典型值);
