数据手册：MAX710, MAX711 紧凑的低噪声、无变压器升/降压调节器，仅使用一只电感，具有低输出纹波 .pdf [英文Rev.0(PDF,152kB)]
{状况：生产中。}
The MAX710/MAX711 integrate a step-up DC-DC converter with a linear regulator to provide step-up/down voltage conversion. They are optimized for battery applications where the input varies above and below the regulated output voltage. They have an input range from +1.8V to +11V. Typical efficiency when boosting battery inputs is 85%.
The MAX710/MAX711 can be configured for minimum noise or optimum efficiency. Shutdown control turns off the part completely, disconnecting the input from the output (ISHDN = 0.2µA). Standby control turns off only the step-up converter and leaves the low-power linear regulator active (IQ = 7µA).
The MAX710 has a preset 3.3V or 5V output voltage. The MAX711 has an adjustable output that can be set from +2.7V to +5.5V with two resistors. Both devices come in 16-pin narrow SO packages.
