The MAX1672EEE+ by Analog Devices is a step-up/step-down DC-DC converter designed for flexible power management in portable devices. It integrates a step-up converter with a linear regulator, enabling it to provide a constant output voltage for input voltages that vary above and below the desired output.
Key electrical specifications include an input voltage range of 1.8V to 11V and an adjustable output voltage from 1.25V to 5.5V, or preset 3.3V/5V outputs. It can deliver up to 300mA of output current at 5V when the input voltage is 2.5V or higher, and 150mA when the input is 1.8V. The device boasts a typical efficiency of 85% and a low quiescent supply current of 85µA, which reduces to 0.1µA in logic-controlled shutdown mode.
The MAX1672EEE+ features a PGI/PGO low-battery detector and includes thermal and short-circuit protection for enhanced reliability. Its unique configuration allows for a smaller inductor compared to SEPIC and flyback designs. The linear regulator component also serves to filter output ripple voltage.
Packaged in a 16-pin QSOP, this component is suitable for surface mount applications. It is designed for use in single-cell lithium-powered devices, 2-cell to 4-cell AA alkaline battery-powered systems, and other low-voltage battery-powered applications.
