General Description
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%.

FEATUREs
♦ Step-Up/Down Voltage Conversion
♦ +1.8V to +11V Input Range
♦ Output: 5V/250mA at VIN = 1.8V 5V/500mA at VIN = 3.6V
♦ No External FETs Required
♦ Load Disconnected from Input in Shutdown
♦ Battery Drain: 200µA No-Load (VIN = 4V) 7µA in Standby 0.2µA when Off
♦ Low-Noise and High-Efficiency Modes
