交叉工作、高效、双电源控制器，用于笔记本电脑

MAX8716/MAX8717/MAX8756/MAX8757是双路、降压型、交错工作、固定频率、开关电源(SMPS)控制器，具有同步整流功能。MAX8716/MAX8717/MAX8756/MAX8757是专门用于产生主电源(5V/3.3V)，而MAX8756经过优化用于为电池供电系统的I/O供电。\n 在从最低到最高26V的电压输入范围内，交错优化的固定开关频率可将输入波纹降至最低。在5V/3.3V应用中，优化的40/60交错工作允许输入电压降低至8.3V而不会出现占空比交叠，而180°异相工作的调节器在输入电压降至10V以下是即出现占空比重叠。\n 可采用检流电阻实现精确的输出电流限制。 \n• 固定开关频率\n• 200kHz、300kHz或500kHz \n• 250kHz、300kHz或400kHz (仅MAX8756) \n• 无需检流电阻 \n• 40/60优化交错 \n• 输入电容要求较低 \n• 固定输出或可调输出(Dual Mode™) \n• 3.3V/5V固定或1V至5.5V可调输出 \n• 1.5V/1.8V固定或1V至2.3V可调输出(仅MAX8756) \n• 4V至26V输入范围 \n• 独立选择PWM、跳脉冲和低噪声工作模式 \n• 软启动和软关断 \n• 0.75%精度的2V基准 \n• 独立电源良好输出;
