-5V/-12V/-15V或可调、高效、低IQ反相DC-DC控制器

MAX774/MAX775/MAX776反相开关稳压器可在负载电流的三个十进位范围内提供高效率。独特的限流、脉冲频率调制(PFM)控制方案提供了脉冲宽度调制的优势（重负载下保持高效率），同时使用小于100µA的电源电流（PWM转换器为2mA至10mA）。由此可在很宽的负载范围内保持高效率。\n\n 这些IC还使用微型外部元件；其高开关频率（高达300kHz）支持使用直径小于5mm的表面贴装磁性元件。\n\n MAX774/MAX775/MAX776支持3V至16.5V的输入电压，预设输出电压分别为-5V、-12V和-15V。或者，用户可以使用两个电阻器来调节输出电压。VIN • 对于5mA至1A负载电流，效率达85%\n\n• 高达5W输出功率\n\n• 电源电流：100µA（最大值）\n\n• 关断电流：5µA（最大值）\n\n• 输入范围：3V至16.5V\n\n• -5V (MAX774)、-12V (MAX775)、-15V (MAX776)或可调输出电压\n\n• 限流PFM控制方案\n\n• 300kHz开关频率;
