4.5V至60V、300mA、超小型、高效率同步降压DC-DC转换器

MAX17570是一款高效率、高电压、同步降压型DC-DC转换器，集成MOSFET，支持4.5V至60V的宽输入电压范围。该转换器在3.3V（MAX17570A、MAX17570D）、5V（MAX17570B、MAX17570E）和可调输出电压（MAX17570C、MAX17570F）下，可提供高达300mA的输出电流。当满足EN/UVLO和VCC UVLO时，内部上电时序将会软启动误差放大器基准电压，从而实现独立于负载电流的干净单调输出电压软启动。VOUT/FB引脚通过电阻分压器监控输出电压。在输出电压达到调节值的95%后1024个周期，RESET引脚转变为高阻抗状态。将EN/UVL • 减少外部元件数量并降低总成本\n• 内部补偿\n• 内部软启动\n• 全陶瓷电容，超紧凑布局\n• 灵活支持系统中的多个电源轨\n• 3.3V和5V固定输出电压\n• 可调输出范围为0.9V至VIN的97%\n• 提供高达300mA的负载电流\n• 200kHz至1MHz可调开关频率，具有外部时钟同步功能\n• 降低功耗\n• 关断电流 = 2.2μA（典型值）\n• PFM选项，可实现出色的轻负载效率;
