MAX17225 Datasheet | Analog Devices

Description The MAX17220- MAX17225 is a family of ultra-low quiescent current boost (step-up) DC-DC converters with a 225m A/0.5A/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 selectable using a single standard 1% resistor. The 225m A (MAX17220/MAX17221), 500m A (MAX17222/ MAX17223), and 1A (MAX17224/MAX17225) peak inductor current limits allow flexibility when choosing inductors. The MAX17220/MAX17222/MAX17224 versions have post-startup enable transient protection (ETP), allowing the output to remain regulated for input voltages down to 400m V, depending on load current. The MAX17220- MAX17225 offer ultra-low quiescent current, small total solution size, and high efficiency throughout the entire load range. The MAX17220- MAX17225 are ideal for battery applications where long battery life is a must.
