MAX17222 500 mA nanoPower Boost Converter

Analog Devices' MAX17222 500 mA nanoPower boost converter feature 0.5 nA shutdown current

Image of Analog Devices' MAX17222 NanoPower Boost ConverterAnalog Devices' MAX17222 is an ultra-low quiescent current boost (step-up) DC-DC converter with a 500 mA 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 MAX17222ELT+ has post-startup enable transient protection (ETP), allowing the output to remain regulated for input voltages down to 400 mV, depending on load current. The MAX17222ELT+ offers ultra-low quiescent current in a small total solution size and high efficiency throughout the entire load range. The MAX17222ELT+ is ideal for battery applications where long battery life is a must.
