MAX1705EEE+T 产品描述
MAX1705/MAX1706是高效率,低噪声,升压型DC-DC转换器与辅助线性稳压器输出。这些设备用于在电池供电的无线应用中使用。他们使用同步整流脉冲宽度调制(PWM)升压拓扑结构,以产生2.5V至5.5V的输出,如1至3个镍镉/镍氢电池或1节锂离子电池,从电池输入。 MAX1705具有内部1A N-通道MOSFET开关。 MAX1706具有0.5A开关。这两款器件还具有一个内置在低压差线性稳压器,可提供高达200mA。
内部同步整流,MAX1705/MAX1706提供更好的效率比同类非同步转换器的5%。他们还配备了一个脉冲频率调制(PFM)待机模式,以提高轻负载时的效率,和1μA的关断模式。一个提高效率的轨道模式,减少上面的线性稳压器输出的升压型DC-DC转换器输出为300mV。
这两种设备都在一个16引脚QSOP封装,占据相同的空间,以便作为一个8针。其他功能还包括两个push-on/push-off控制关断控制输入,电压监视器使用的未比较。
