点击查看特定型号的库存状况。

说明

MAX1966/MAX1967是电压模式脉宽调制(PWM)、降压型DC-DC控制器,非常适合那些对成本要求苛刻的应用。这些器件驱动廉价的N沟道MOSFET高端开关和同步整流器,并且不需要外部的肖特基功率二极管或检流电阻。通过检测低端FET的漏-源电压提供短路和限流保护。两款器件都可提供低至0.8V的输出电压,非常适合DSP内核及其他低电压逻辑电路的供电。

MAX1966输入电压范围是2.7V至5.5V;MAX1967输入电压范围是2.7V至28V。在超低成本设计中,MAX1966/MAX1967可提供高于90%的效率,通过优化选择外部元件效率可以达到95%。

MAX1966/MAX1967工作频率为100kHz,在低成本设计中允许使用铝电解电容和铁粉磁芯。如果选用高性能的表贴元件,它们还能够提供更出色的性能指标。MAX1966采用低成本的8引脚SO封装,MAX1967采用10引脚µMAX封装。
