The MAX1672EEE by Analog Devices is a step-up/down DC-DC converter designed for applications requiring a constant output voltage from a varying input. It features a wide input voltage range from 1.8V to 11V and can provide a preset 3.3V or 5V output, or an adjustable output from 1.25V to 5.5V. This device integrates a step-up converter with a linear regulator, allowing it to handle input voltages above or below the desired output.
Key electrical characteristics include an output current capability of up to 300mA at 5V (when VIN is 2.5V or higher) and a typical efficiency of 85%. The device operates with a low quiescent supply current of 85µA, which can be reduced to 0.1µA in logic-controlled shutdown mode. The linear regulator component also serves to filter output ripple voltage.
Designed for space-constrained applications, the MAX1672EEE is housed in a compact 16-pin QSOP package, offering the same footprint as a standard 8-pin SO package. It requires no external FETs and includes thermal and short-circuit protection. Applications include single-cell lithium-powered portable devices, 2-cell to 4-cell AA alkaline battery-powered equipment, and 3.3V systems with AC input adapters.
