The MAX17291 is a low quiescent current boost (step-up) DC-DC converter with a 1A peak inductor current limit and True Shutdown™. True Shutdown disconnects the output from the input with no forward or reverse current. The output voltage is set with an external resistor-divider.

The MAX17291 offers low quiescent current, small total solution size, and high efficiency throughout the entire load range. The MAX17291 is a highly integrated boost converter designed for applications requiring high voltage and tiny solution size, such as sensor modules. It integrates a power switch, power diode, and output load switch. It can output up to 20V. The load switch is turned off under shutdown mode, truly disconnecting the load from the input voltage, thus minimizing the leakage current during shutdown mode. The device operates with a switching frequency of 1.0MHz in continuous conduction mode (CCM). The MAX17291 switch current limit is 1A. It has 2.2ms built-in soft-start time to minimize inrush current. The device features short-circuit and thermal protection.

The MAX17291 is offered in space-saving, cost-effective 1.27mm x 0.87mm, 6-bump WLP (3 x 2, 0.4mm pitch) and 2mm x 2mm, 8-pin TDFN packages. The operating temperature range is from -40°C to +125°C.
