Maxim MAX17250 DC-DC Boost Converter with 0.1 μA True Shutdown Mode at Mouser

Mouser Electronics is now stocking the MAX17250 DC-DC synchronous boost converter from Maxim Integrated. The MAX17250 offers up to 93 percent efficiency to minimize heat dissipation, with an ultra-low quiescent current that helps extend battery life in digital cameras, battery-powered Internet of Things (IoT) devices, and other connected designs.

The Maxim MAX17250 DC-DC boost converter includes a selectable input peak current limit of 3.5 A, 2.7 A, or 1.85 A and operates over an input voltage range of 2.7 V to 18 V with an output voltage range of 3 V to 18 V. The device supports switching frequencies up to 1 MHz and offers short-circuit protection and a maximum on-time of 800 ns in a space-saving 12-bump, 1.72 mm × 1.49 mm package.

The MAX17250 converter implements three modes of operation: The first mode of operation is a soft-start mode at power-up. The second mode of operation is normal operation, which uses a fixed on-time/minimum off-time pulse frequency modulation (PFM) architecture that uses only 60 μA (typical) quiescent current due to the converter switching only when needed. The MAX17250 converter’s True Shutdown mode completely disconnects the output from the input, resulting in a current draw of just 0.1 μA, virtually stopping battery drain, providing long battery life, and eliminating the need for external disconnect switches.

Mouser is also stocking the Maxim MAX17250EVKIT#WLP evaluation kit, a fully assembled and tested kit that incorporates the MAX17250 converter and provides resistor-configurable output voltages from 3 V to 18 V.
