The MAXM17225 is a nanoPower, ultra-low-IQ (300nA) boost module offered in a tiny eMGA package. The IC is guaranteed to startup with voltages as low as 0.88V and post startup, the input voltage V_IN can go down to 0.4V making it ideal for battery-operated devices that undergo voltage discharge over time. Its ultra-low quiescent current of 300nA prolongs battery life and extends product lifetime as well. The IC accepts input voltage from 0.4V to 5.5V and boosts it up to programmable output voltages from 1.8V to 5V. The output voltage is set using a single external resistor (R_SEL). The product has a maximum efficiency of 95%. The module is well suited for a host of applications like battery-operated devices, portable electronics where step-up conversion is needed in space constrained enclosures while demanding high efficiency. A true shutdown disconnects the input from the output, conserving battery life. The IC has an integrated 1µH inductor chosen for optimized operation, stability, and efficiency. Guaranteed Boost V_OUT regulation for 250mV separation between input and output voltages while driving heavy loads. A single external selectable resistor (R_SEL) for V_OUT setting reduces quiescent current consumption in comparison with a conventional resistor feedback divider string. The MAXM17225 has a fixed maximum 300ns switch turn-on time and peak inductor current limit of 1A. The IC auto-transitions between the ULPM, LPM, and HP operating modes based on load current, enabling better system transient response and efficiency. All these powerful features are packed in a tiny 10-lead eMGA package offering the end designer an efficient tool to design products.
