5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers

General Description The MAX770–MAX773 step-up switching controllers provide 90 efficiency over a 10mA to 1A load. A unique current-limited pulse-frequency-modulation (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) converters (high efficiency at heavy loads)

5V/12V/15V或可调、高效率、低IQ、升压型DC-DC控制器

MAX770-MAX773升压型开关控制器可在10mA至1A负载范围内达到90%的效率。这些器件采用专门设计的限流脉冲频率调制(PFM)控制方案，具有脉冲宽度调制(PWM)转换器的优势（重负载时效率高），同时电源电流小于110µA（PWM转换器的电源电流为2mA至10mA）。\n\n 这些IC使用小型外部元件。其具有高开关频率（高达300kHz），支持使用表面贴装5mm（高）x 9mm（直径）的磁性元件。\n\n MAX770/MAX771/MAX772支持2V至16.5V的输入电压。输出电压预设为5V (MAX770)、12V (MAX771)和15V (MAX7 • 对于10mA至1A负载电流，效率达90%\n\n• 高达15W输出功率\n\n• 电源电流：110µA（最大值）\n\n• 关断电流：5µA（最大值）\n\n• 输入范围：2V至16.5V (MAX770/MAX771/MAX772)\n\n• 内部分流调节器支持高输入电压(MAX773)\n\n• 预设或可调输出电压\n• MAX770：5V或可调\n\n• MAX771：12V或可调\n\n• MAX772：15V或可调\n\n• MAX773：5V、12V、15V或可调\n\n\n\n\n• 限流PFM控制方案\n\n• 300kHz开关频率;
