双路、高效率、PFM、升压型DC-DC控制器

MAX863双路输出DC-DC转换器采用紧凑的封装，包含两个独立的升压控制器。当两个控制器都打开时，这种单片Bi-CMOS设计仅消耗85µA。输入范围低至1.5V，允许用于组织整理工具、翻译器和其他低功率手持产品。MAX863在20mA至1A以上的输出负载下提供90%的效率。这种节省空间的器件采用16引脚QSOP封装，与8引脚SOIC的面积相同。\n\n 该器件采用限流、脉冲频率调制(PFM)控制架构，可降低启动浪涌电流并保持低静态电流，以实现出色的低电流效率。每个控制器驱动一个低成本的外部N沟道MOSFET开关，其尺寸可以针对任何输出电流或电压进行优化。\n\n • 超小的双路升压转换器：16引脚QSOP\n\n• 90%效率\n\n• 1.5V启动电压\n\n• 总静态电源电流：85µA（最大值）\n\n• 关断模式下为1µA\n\n• 独立关断输入\n\n• 驱动表面贴装、双N沟道MOSFET\n\n• 低电池输入/输出比较器\n\n• 升压/降压可配置;
