带外部软启动功能的同步降压变换器

MP4569 是一款集成了上下管高压功率 MOSFET 的降压开关调节器。它可以提供高达 0.3A 的高效输出。\n\n4.5V 至 75V 宽输入范围使其适用于汽车环境中的各种降压应用。3.5μA 的关断模式静态电流非常适用于电池供电应用。\n\n在轻载条件下，可通过降低开关频率在宽负载范围内实现高转换效率，以减少开关和栅极驱动器损耗。\n\n开关频率降低功能可以防止启动时或短路时电感电流过冲。过温关断保护确保了工作的稳定性和可靠性。\n\nMP4569 采用 QFN-10（3mmx3mm）和 SOIC-8 EP 封装。 • 20μA 静态电流（有源模式）\n• 4.5V 至 75V 宽工作输入电压范围\n• 1.2Ω/0.45Ω 内部功率 MOSFET\n• 可编程的软启动功能\n• 反馈公差：室温下为 1%；全温下为 2%。\n• 可调输出\n• QFN 封装参考电压输出为 1V\n• 低关断模式电流：3.5μA\n• 采用 QFN-10（3mmx3mm）和 SOIC-8 EP 封装;
